T In the early months of the COVID-19 pandemic with no designated cure or vaccine, the only way to break the infection chain is self-isolation and maintaining the physical distancing. In this article, we present a potential application of the Internet of Things (IoT) in healthcare and physical distance monitoring for pandemic situations. The proposed framework consists of three parts: a lightweight and lowcost IoT node, a smartphone application (app), and fog-based Machine Learning (ML) tools for data analysis and diagnosis. The IoT node tracks health parameters, including body temperature, cough rate, respiratory rate, and blood oxygen saturation, then updates the smartphone app to display the user health conditions. The app notifies the user to maintain a physical distance of 2 m (or 6 ft), which is a key factor in controlling virus spread. In addition, a Fuzzy Mamdani system (running at the fog server) considers the environmental risk and user health conditions to predict the risk of spreading infection in real time. The environmental risk conveys from the virtual zone concept and provides updated information for different places. Two scenarios are considered for the communication between the IoT node and fog server, 4G/5G/WiFi, or LoRa, which can be selected based on environmental constraints. The required energy usage and bandwidth (BW) are compared for various event scenarios. The COVID-SAFE framework can assist in minimizing the coronavirus exposure risk.

With the help of artificial intelligence, this novel smart device is handy for maintaining a social distancing as well as detecting COVID 19 symptom patients and thereby safety. In these COVID-19 environments, where everyone is conscious about their safety, we came up with the idea of this novel device. Most of the time, people on the roadside watched their front but were not able to look after what is going on behind them. The device will give alert to the person if someone in the critical range of six feet around him. The method is reasonably accurate and can be very useful in maintaining social distancing. The sensor model used is described, and the expected errors in distance estimates are analysed and modelled. Finally, the experimental results are presented.

At present time, drowsy driving has become one of the major issues of the traffic collision. According to statistics, a large number of road accidents occur due to drowsy driving which results in severe injuries and deaths. For this reason, various studies were done in designing systems that can examine the driver fatigue and alert him beforehand, thus preventing him to fall asleep behind the wheel and cause an accident. Some traditional approaches used vehicle-based measures to design their system, however, such measurements are highly influenced by the structure of the road, type of vehicle and the driving skill. Other approaches used psychological measures for their system that tend to provide better accuracy in monitoring the drowsiness of the driver. However, such techniques are usually intrusive as electrodes are required to be placed on the head and body. Furthermore, there are few existing researches in which subjective measurements are used as the input for the system, but, such methods can distract the driver and lead to an ambiguous result. In this paper, we proposed a system that is absolutely non-intrusive and real-time. Our proposed system used the eye closure ratio as input parameter to detect the drowsiness of the driver. If the eye closure ratio deteriorates from the standard ratio, the driver is alerted with the help of a buzzer. For our system, a Pi camera is used to capture the images of the driver’s eye and the entire system is incorporated using Raspberry-Pi.

This allows users to check for available parking spaces online from anywhere and avail hassle free parking. Thus the system solves the parking issue for cities and get users an efficient IOT based parking management system.

Keeping the city clean has been always an ongoing task which needs laborious efforts of people working on ground level emptying the garbage bins whenever they are full. The event of garbage bin getting full is not strictly dependent on a time pattern, instead it sometimes becomes rapidly full or sometimes requires more than normal time to become full. IOT Garbage Monitoring with Weight Sensing project is an innovative step towards making this process more smooth and efficient.
This system monitors the garbage bins and informs about the level of garbage collected in the garbage bins via a web page. For this the system uses ultrasonic sensors placed over the bins to detect the garbage level and compare it with the garbage bins depth. In addition, we also have weight sensors attached below the garbage bins. Thus the system sends over the internet the level of fill of the garbage bins as well as the weight of the fill of the garbage bins.

The web page gives a graphical view of the containers and highlights the liquid level in color in order to show the level of liquid. The LCD screen shows the status of the liquid level. 

It is quite difficult for individual office owners to operate one or more that one offices and keep track of each office appliances individually. At such time we need an online solution for physical office appliances control. Her we propose use of iot technology for office appliance automation. This allows owner co control his/her office appliances through the internet using an easy to use GUI. For this system demonstration our system uses an AVR family microcontroller for the purpose. A wifi modem is used for receiving commands over the internet. We use 3 loads and a fan to demonstrate as office loads. A wifi modem is used to receive commands over the internet. The wifi module receives user commands over the internet. This information is then passed on n to the microcontroller. The microcontroller now processes this data and switches the loads through relays. Also it switches the fan as per users commands. Also it displays the status of the system on an LCD screen. Thus office automation system allows user to control his office remotely using IOT technology.

All wireless communication systems work on antennas for reception of signals. Proper positioning of antennas is necessary according to satellites/transmitters to achieve effective wireless communication. So here we propose an IOT based antenna positioning system that allows for remotely positioning of antennas based over IOT. Here we use sensor based system with motor on each antenna using antenna to check its facing direction that is transmitted over IOT. If the direction of a satellite or transmitting station changes over time, the antenna direction must also be changed accordingly. The receiving antennas may be placed far apart from each other across the globe. So our system allows for antenna positioning over very long distances. The antenna positions are visible over internet to controlling operator on the IOT

Here we propose an IOT based street light monitoring and controlling system to ensure, low power consumption, consumption monitoring, instant faulty light detection and light dimming as per external lighting conditions. Our proposed system consists of smart street lights that have external light sensing that automatically turns on at desired intensity based on amount of lighting needed. The system also allows the controller/monitoring person to check estimate power consumptions as per current intensity of light as well as predict monthly power consumption. Also each of the unit has load sensing functionality that allows it to detect if the light has a fault. It then automatically flags that light is faulty and this data is sent over to the IOT monitoring system so that action can be taken to fix it. 

Underground cables are prone to a wide variety of faults due to underground conditions, wear and tear, rodents etc. Also detecting fault source is difficult and entire line is to be dug in order to check entire line and fix faults. So here we propose an cable fault detection over IOT that detects the exact fault position over iot that makes repairing work very easy. The repairmen know exactly which part has fault and only that area is to be dug to detect the fault source. This saves a lot of time, money and efforts and also allows to service underground cables faster. We use IOT technology that allows the authorities to monitor and check faults over internet. 

When it comes to old age, it becomes necessary to monitor our old ones for their health and safety. Due to weakness and weak joints they have a great risk of falling down. Now it is important to know if an old age person has fallen so that he/she can be helped on time. Also people on wheelchair need to be checked for fall detection. For this purpose we propose a smart fall detection system. The system uses accelerometer and gyro sensor to detect person movements, It can be mounted on persons hand or wheelchair for detection. The sensor is connected to a microcontroller in order to constantly transmit the acceleration data. Now the system keeps monitoring for fall detection and abrupt movement changes in person. A sudden abrupt change with jerk in the system is treated as a fall. 

Managing multiple toll booths is a very complicated task. We here propose a smart card based toll booth system that is monitored over IOT. The Internet server maintains all the data of user accounts and also their balance. All vehicle owners would possess an rfid based card that stores their account number. Our system at toll booths will monitor the cards scanned when a car arrives at the toll booth. The system now connects to the online server to check if the card is valid and if valid what is the balance. If user balance is sufficient, the user balance is deducted online and web system sends signal back to the card scanner system that the user has been billed. On receiving this signal the system operates a motor to open the toll gate for that car. The system is controlled by a microcontroller to achieve this purpose. The microcontroller uses wifi connection to connect to the internet through which system interacts with web server to perform the online verification process. 

With progress in human technology we have seen a substantial progress in the amount of waste generated. Recycling is the only way to manage this huge amount of waste. But recycling requires garbage to be segregated. Without segregation garbage cannot be recycled because different type of garbage requires different recycling processes.
Also It is important to educate users and instruct them every time they come near the dustbin about instructions about throwing the trash. For this purpose we design a garbage disposal system that uses multiple dustbins with a voice based system that speaks to the user each time he she stands before the dustbin.
The system makes use of a camera to detect presence if any person in front of the dustbin. If a person is detected, the system issues voice instructions to the user about throwing right garbage in the right bin. In case the dustbin is full it instructs the user to find another dustbin to throw garbage in.
To develop this system we make use of a raspberry Pi controller. The controller is interfaced with a camera and a voice speaker for detection and communication. The controller gets dustbin level input using ultrasonic level sensors each having LED indicators interfaced to it. The level sensors are used to constantly feed the raspberry pi with bin levels.

Social distancing is of key importance during the current pandemic. It helps limit the spread of covid by observing distance between disease spreading individuals. Now it is not possible to station a person 24×7 at each queue to monitor social distancing violations. Banks, Public Offices, Malls, Schools, Theatres etc usually see long queues for hours every day. To ensure social distancing in queues we hereby design a social distancing monitoring robot.
The robot consists of a 4 wheel design system used to drive the robotic vehicle. It makes use of a line following principle to constantly move along with the queue and monitor for social distancing violations. The robotic uses IR sensing to travel along with the queue to and fro in order to detect violations. The robot is now equipped with obstacle detecting ultrasonic sensor in order to detect obstacles in the vehicle path.

In view of current pandemic covid testing plays a key role in fighting the pandemic. Covid testing is done in covid testing booths that provide a safe covid testing environment. Now the testing process involves the following steps

• Registering the person name, contact no address manually
• Taking a swab sample of the person
• Adding the swab sample number against the persons registered details
• Sending the data along with the samples to the lab
• Manually informing (calling/sms) the patient about the result

Now this is a very long process with a lot of manual steps which can lead to human errors because of huge amount of samples coming in for testing. So here we propose a system whereby we automate around 70 % of the manual entry work and allow for a single point and fast covid testing system using IOT.

Nowadays, accidents due to broken and missing manhole covers are quite frequent. Manholes are not monitored properly in developing countries. These accidents can lead to serious injuries and also death. Hence, here we propose a system to overcome this problem. We have included an array of sensors for complete monitoring of the manhole cover so that such accidents can be prevented. This project includes a gas cover to monitor the gas emitted from the sewage systems so that toxicity can be monitored, the internal temperature is also monitored if a check for a change in the temperature as the property of manhole change with temperature which could need to crack formation, a tilt sensor is introduced to indicate whether the manhole can tilt. Also, a float sensor is used to indicate when the water level goes beyond a certain level, in case of any alert due to any of the parameters we send an SMS to an authority number as well as on the IOT website. Also, all the parameters are continuously updated on the website.

When one phase of a three-phase system gets lost, a phase loss occurs. This is referred as a ‘single phasing’, this failure generally caused by a blown fuse, thermal overload, broken wire, worn contact or mechanical failure. This is an advanced system that monitors power failure. There are three phases R, Y, and B when any one of the phases detects failure it notifies the concerned authority with the help of text message. This IOT system is connected with the GSM module, the call is connected for configuration purpose. Whenever the phases are been disconnected the system shows the power failure on LCD indicating voltage value and then it raises a buzzer. Then it sends SMS on the authorized number informing the disconnected phase. After reconnecting power to the phase system, raises a buzzer and sends the text message informing the phase is working fine, on the authority person number. In this way, the authority gets instantly notified and they may take appropriate action to solve the problem.

The rapid rise of technology and infrastructure has made our lives easier. The high demand of automobiles has also increased the traffic hazards and road accidents. Life of the people is under high risk. The delay in reaching of the ambulance to the accident location and the traffic congestion in between accident location and hospital increases the chances of death of the victim. To overcome this problem our automatic ambulance rescue system comes to the rescue. This proposed IOT based accident detection system helps to reduce the loss of life due to accidents and also reduces the time taken by the ambulance to reach the hospital. To detect the accident there is accelerometer sensor present in this rescue system and the GSM module included sends messages about the location to the respective guardian and rescue team. With the help of accelerometer sensor signal, a severe accident due to an obstacle can be recognized. Microcontroller used, sends the alert message through the GSM module including the location to guardian or a rescue team. So, the emergency help team can immediately trace the location through the GPS module, after receiving the accident location information, action can be taken immediately. This accelerometer based accident detection system is powered by Atmega 328 microcontroller it consists of display, accelerometer sensor, GSM module and alarm. This automatic ambulance rescue system project is useful in detecting the accident.

Coal mining is the process of extracting coal from the ground. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. Underground mining industry comes to the category, where each and every parameter such as methane gas, high temperature, fire accidents and so on has to be monitored regularly. Safe production level of coal mine is still low, disasters in coal mine occur frequently, which lead to great loss of possession and life. The disasters happening in coal mine are due to the complexity of mine environment and the variety of work carried out in coal mine, so it is very necessary to monitor the working environment of coal mine. To get over this problem, Nevon projects has proposed a wireless sensor network’s application in coal mining safety system. In this wireless sensor network’s application system there will, be master controllers and slave controllers. Slave controllers will detect the danger and give alert through RF to master controller and it will raise the alarm in all tunnels and also raise message on IOT, which will help to take action as soon as possible. This monitoring and alerting system is powered by Atmega328 microcontroller for master controller and 8051 micro controllers for slave controllers. 8051 micro controller consists of temperature sensor, water sensor, methane and carbon dioxide sensor and RF transmitter which collects temperature, humidity and methane values underground of coal mine.

Energy crisis is one of the major problems that the world faces today. The energy crisis can be reduced to a certain extent by properly monitoring our energy consumption and avoiding energy wastage. Nowadays people face many problems like power theft. Power theft may be a measure crime and it also directly affects the economy of our country. This system will find energy theft easily. This IOT electricity meter is consisting of Atmega 328 microcontroller with a WIFI module for IOT connection and GSM module for mobile connection, on which users will receive information via SMS. This smart electricity meter also consists of a current sensor that sends the current reading to the microcontroller. We have to connect cell phones with the system via SMS which will help to configure with the system. In case of an emergency, the information will be shared on the configured number.

Many accidents occur in day to day life like explosion because of LPG leakage. Major harm is caused, if gas leakage is not detected early. But now we can detect the gas leakage using the MQ5 gas sensor. In this IOT gas leakage detector, device will get connected to WIFI, the minimum and maximum parameter can be set accordingly. Such IOT as well as Arduino based gas leakage detector systems can be installed in homes, hotels LPG gas storage areas. In this LPG gas detector system senses the LPG gas using MQ5 gas sensor. This device will continuously monitor the level of LPG gas present in the air. While monitoring, if the value of LPG gas in air is within the set limit then the RGB LED on the circuit will glow green giving a safe sign. And whenever the gas exceeds above the predefined limit than the RGB LED will glow red and simultaneously solenoid value will turn off and update it over IOT. This Arduino and IOT project will help in detecting gas leakage in the surrounding.

Gas leaks within the home are usually the results of poorly fitted, badly maintained or faulty appliances like boilers and cookers. There are several deaths per year linked to gas leaks in addition to hundreds of hospitalizations, gas safety is something every household should take seriously. To reduce this accident, we can detect the gas leakage using the MQ5 gas sensor. Firstly, when we turn on the power to the circuit, the project automatically gets connected to the WIFI and the IOT site, once the connection to Wi-Fi and the IOT site is established, the system waits for the user to manually enter the minimum and maximum values on the IOT site, once the user enters the data is received by the system. 

The Embedded technology has entered almost in all aspects of day-to-day life, and the healthcare field is no exception for that the requirement for fully-equipped hospitals and diagnostic centers growing day by day as people are becoming more unaware of their health problems. An ECG signal can trace various physiological and abnormal conditions of the heart. This heart monitoring system also helps to inform the person whether he/she has any heart diseases or not. This is done by checking the heart beat level. In this system Atmega controller is used to scan ECG signal and search for pattern in common range, if the pattern will be in normal range then it gives the report of being normal if it is found that it is not in normal range then the person is suffering from some kind of heart disease. The following result is sent as an alert message on IOT. 

As we know coma is a state of unconsciousness in which patient cannot feel or respond to the pain, light or sound, it does not initiate volunteering any actions. Patients in a coma state need to have a continuous update of Blood pressure, temperature, humidity, and urine level. Doing this manually can become almost impossible to keep updates of multiple patients at the same time. In order to address this situation, our system comes to the rescue; this system will collect the information of patients with the help of sensors. These sensors use WIFI to communicate this information to the internet. This system is powered by the Raspberry Pi it includes a blood pressure monitoring unit and an ultrasonic sensor to check urine, temperature sensor, motion sensor, and an LCD display.
When we turn the system on, it gets connected to the website using WIFI, System monitor shows four signs namely heart rate, temperature, humidity, and urine output.
