This paper describes the development of a heart rate monitor system based on a microcontroller. It offers the advantage of portability over tape-based recording systems. The paper explains how a single-chip microcontroller can be used to analyse heart beat rate signals in real-time. In addition, it allows doctors to get the heart beat rate file of the patient by email every twenty four hours. It can also be used to control patients or athletic person over a long period. The system reads, stores and analyses the heart beat rate signals repetitively in real-time.

The hardware and software design are oriented towards a single-chip microcontroller-based system, hence minimizing the size. The important feature of this paper is the use of zero crossing algorithm to compute heart rate. It then processes on real-time the information to determine some heart diseases.

In this paper, we propose a Simple Wireless transmission System using common approach Sensor Platform called The wireless based Patient Sensor platform (WSP, Sensor Node) which has remote access capability.

The goals of the WSP are to establish: Standard sensor node (System on module),  a common software. The proposed platform architecture (Sensor Node) offers flexibility, easy customization for different vital parameter collecting and sending.

An prototype has been established based on wireless communication channel. Wireless lan (IEEE.802.15.4) has been used as communication channel on our prototype (Sensor node). Desire sensor information (vital parameter) can be viewed remotely, and also vital parameter can be adjusted to meet demand.

The proposed system is used to monitor the health condition of the patient like pulse rate, temperature, and humidity using sensors. These sensors get information from the health parameters. Once the sensors get the data, it sends it to the Microcontroller. After that, the microcontroller transmits to the user through an SMS with the help of a GSM modem. Finally, this data can be displayed over LCD. If the readings of the patient on display are abnormal then an alarm can be generated.

SMS based Baby Incubator using GSM technology has main application in Hospitals. SMS is sent to the user whenever Temperature or Humidity crosses threshold level. This user should be Doctor or care taking person of baby. Whenever Temperature rises above a threshold level at that time a Relay is turned on.Arduino &IOT based

The appearance of wearable monitors devices that are connected via clinic networks or control center. It allows doctors to monitor sounds, images, body movement and vital signs such as blood pressure, body temperature, heart rate, pulse, body weight, and oxidized blood.

This project performs three main functions. First one is Patient health monitoring; second one is tracking the Ambulance which is carrying the Patient and third one is to send above two details to the Hospital or Doctor using a GSM technology. With the help of this project we can find out the location of ambulance and at the same time we can monitor various health parameter of a patient. These parameters are temperature, humidity and heart beat rate. A text SMS containing location and values of all the sensors is sent to a Doctor’s mobile. Or we can send this text SMS to any authorized person in hospital. Then that person can intimate Doctor about ambulance location and health. By using these parameters, doctor can do the necessary preparation for treatment of patient. It uses Visual basic software at PC in monitoring system to display location of ambulance by using Google earth map and displaying SMS. After receiving SMS hospital can prepare their staff for proper treatment of coming patient.

t-Nowadays all nations keep its security at high priority. Wars are being fought for land, water and acquiring the position of most powerful nation. A country’s arm forces consist of three professional uniformed services: the army, the navy, and the air force. Soldiers being the backbone of any armed force usually lose their lives due to lack of medical help when in emergency, also soldiers who are involved in missions or in special operations get straggled on war fields and lose contact with the authorities. To overcome this concerns we had build this project which, using wireless body area sensor network (WBANS) such as temperature sensor, heartbeat sensor etc. will monitor the health status of the soldier whenever required. Also using GPS we can track the soldier’s exact location whenever required. Using oxygen level sensor we can also monitor the environmental condition, so authorities can provide essential aids. The communication is established between the soldiers and authorities via GSM. Any abnormalities in the readings of wireless body area sensor network (WBASNs) is considered as a trigger for GSM to establish the connection between the soldier and base unit and send current location and health status to the receiver. By using all this equipments we had tried to implement the basic guarding system for the soldier in low cost, light weighted, portable and precise device.

COVID 19 has made a huge impact on the society, the new restriction has been imposed as in the number of users allowed in a particular room in offices, shops, etc. to maintain social distancing, along with social distancing regular temperature check at entrances of malls, the office is mandatory. In this project we stimulate a room where such necessary precautions are taken, we make use of a laser diode and receiver to detect the entrance of a person, when the project detect entrance it will check the temperature of the person if the temperature is less than the set temperature the person is allowed entry otherwise the entry is denied. only a pre-determined number of people are allowed in the room. The allowed temperature, the number of people allowed in the room as well as the number of people actively present in the room can be set/viewed using a Bluetooth App.

Monitoring your beloved ones becomes a difficult task in the modern day life. Keeping track of the health status of the your patient at home is a difficult task. Specially old age patients should be periodically monitored and their loved ones need to be informed about their health status from time to time while at work. So we propose an innovative system that automated this task with ease. Our system puts forward a smart patient health tracking system that uses Sensors to track patient health and uses internet to inform their loved ones in case of any issues. Our system uses temperature as well as heartbeat sensing to keep track of patient health. The sensors are connected to a microcontroller to track the status which is in turn interfaced to an lcd display as well as wifi connection in order to transmit alerts. If system detects any abrupt changes in patient heartbeat or body temperature, the system automatically alerts the user about the patients status over IOT and also shows details of heartbeat and temperature of patient live over the internet. Thus IOT based patient health tracking system effectively uses internet to monitor patient health stats and save lives on time.

Coma is a state of unconsciousness where the patient fails to respond. These patients need utmost care and 24*7 observations. This paper presents a continuous monitoring and recording of patient data without human intervention. If there is any sudden changes occur in the normal range of body parameters such as body temp falls or rise, blood pressure (B. P.) increases or decreases causing high or low B.P. where both are not stable conditions for better health, then it has facility to automatically alert the medical person. The movement sensor detects the patient movement and also generates an alert message to the medical person. As comatose losses their sensation for urination, medical person needs to continuously monitor urine output, thus we are using ultrasonic sensor to check on urine level. Medical person can keep the track of patient using login to the system. The software IoT API we are using isThingSpeak.

Heart rate, body temperature and blood pressure are very critical parameters of human body. Doctors use various kinds of medical apparatus for measurement of these parameters like thermometer for checking body temperature, BP monitor for blood pressure measurement and heart rate monitor for heart rate measurement. In this paper, we have proposed ECG MONITORING SYSTEM based on IoT (Internet Of Things). This system calculates heart rate of patient and sends the value of heart rate in beats per minute (bpm) to a database on cloud. Using this system doctors at hospital can analyse the critical parameters sent by this system. Doctors can also analyse the real time health related parameters of a patients which are not admitted in hospital. This system can be integrated in ambulance wherein all the critical health related parameters of patients can be acquired and sent to the cloud. All these critical parameters can be analysed by a doctor in advance while the patient is still in ambulance. The main objective of this system is to acquire the physiological parameter using sensors and uploading these parameters to cloud. We have integrated ECG sensor in this system.

These days we have an increased number of heart diseases including increased risk of heart attacks. Our proposed system users sensors that allow to detect heart rate of a person using heartbeat sensing even if the person is at home. The sensor is then interfaced to a microcontroller that allows checking heart rate readings and transmitting them over internet. The user may set the high as well as low levels of heart beat limit. After setting these limits, the system starts monitoring and as soon as patient heart beat goes above a certain limit, the system sends an alert to the controller which then transmits this over the internet and alerts the doctors as well as concerned users. Also the system alerts for lower heartbeats. Whenever the user logs on for monitoring, the system also displays the live heart rate of the patient. Thus concerned ones may monitor heart rate as well get an alert of heart attack to the patient immediately from anywhere and the person can be saved on time.

Factories, Offices, Hospitals, Military and other such industries need to monitor their staff/personnel follow all work ethics that include, not coming to premises under the influence of alcohol or under bad health conditions. This ensures proper work ethics are followed. So our proposed system allows for alcohol & health monitoring plus reporting system that monitors this and reports it to concerned personnel remotely over internet. Our system consists of an IOT based circuit system that uses a microcontroller based circuit system. The system has alcohol as well as blood pressure monitoring sensors to check for alcohol consumption as well as inappropriate blood pressure monitoring. This ensures no occurrences of accidents due to alcohol influence or bad health conditions.

IOT Based ICU Patient Monitoring System: IOT (Internet of Things) based ICU (Intensive Care Unit) patient monitoring system is a system, which measures the patient blood pressure, heart beat rate and temperature constantly who is admit in ICU room. After measuring, this system also sends this data to dedicated website through IOT system. If we see in our society then we can easily analyse, that our hospitals are full of patients. For look after these patients, so much hospital staff means doctors or nurses are required which is not possible in every hospital. Beside this, look after of individual patient specially which are admit in ICU room whose temperature and blood pressure measurement reading is so much necessary in every single moment is also a big problem. On concentrating these problems here we have proposed a system that is a called IOT based ICU patient monitoring system with help of avr microcontroller Atmega48, temperature and humidity sensor, blood pressure sensor, IOT system and LCD display. This system would be measure automatically the patient body temperature, blood pressure and send this measured data on dedicated website. Where every respective doctor could easily see their respective patient data all the time from any place. This system is less costly and more precise as compared to the other systems.

We come across hospitals and NGO‟s serving disabled people. Now these people are not capable of full body movement as compared to a normal person. In such a situation we propose a system that helps disabled person display a message by just simple motion of any part of his body. Our proposed system works by reading the tilt direction of the user part. This device needs to be mounted on user finger of hand. The user now just needs to tilt the device in a particular angle to convey a message. Tilting the device in different directions conveys a different message.

Due to the widespread fear caused by the highly infectious COVID-19, businesses and workplaces are apprehensive to resume operations like before. With no signs of this pandemic fading away in the near future, workers will have to adhere to live with it and take precautionary measures while going about their daily tasks. In short, this will become the “new normal”.

Furthermore, the reliance on contactless technology will increase in order to curb the spread of infection through touch. However, the current large scale usage of touch-based biometrics for attendance and access control pose a challenge. At the same time, manually-based temperature screening methods are not accurate enough.

The idea of this project expands upon the incorporation of wireless communications into medicinal applications to revolutionize personal health care .The goal of our venture is to build a wireless heart beat monitoring framework utilizing GSM Technology, which could conceivably be a fundamental piece of individual healthcare apparatuses. As its name infers this is a system, having characteristic of sending SMS to both the doctor & patients relative in event of an emergency, henceforth the system can be utilized at clinics, hospitals and in addition at home.

Now a day’s Heart attack is a common one which affects almost 60% of total population due to their food conditions and various environmental factors. Still now there is no separate system for the intimation of heart attack. After the occurrence of heart attack only, the patient can be monitored. Only pre possible solution for the detection of heart attack is by analysing the number of beats per minute (BPM). So this work detects the heart attack based on the number of pulses. If the pulse rate other than the range (60-90) occurs it is considered as the indication of heart attack. Addition to this detection of heart attack, this work intimates the occurrence of heart attack to the helpline in wireless GSM module. In this work, a system to detect heart attack is designed and developed. A pulse sensor is used for sensing the heart beat signals. The microcontroller checks these signals and counts the pulses. If the pulses are greater or less than certain levels, the controller activates GSM module and sends an alert message to mobile numbers already coded in a microcontroller. The developed system is tested with the measurement of different male and female persons. The system performed accurate detection and intimation of messages to the different care takers of the patients. Many lives may be saved in the short duration by using this developed system.
