As it was stated earlier, it is seen in a number of cities that the street light is one of the huge expenses in a city. The cost spent is huge that all the sodium vapor lamps consume more power. The expense spent on the street light can be used for other development of the nation. Currently a manual system is used where the light will be made to switched ON/OFF i.e. the light will be made to switch ON in the evening and switched OFF in the morning. Hence there is a lot of wastage of energy between the ON/OFF. This is one of the major causes of shifting to the automatic system, since there is less wastage of power and thus saving a lot of monetary expenses. Apart from this, the other disadvantages of the existing system are described below.

Utilization of power turns to be necessary for every work in today’s world. To comfort our daily routines the devices are used in large numbers. The benefits of roadway energy harvesting systems are potentially excellent. Energy harvesting is defined as capturing minute amounts of energy from one or more of the surrounding energy resources. To generate the power through footsteps as a source of renewable energy sources that we can obtain while walking on a certain arrangement like stepping foot on piezoelectric tiles. an advanced footstep power generation system proposed here uses the piezoelectric sensors. To generate a voltage from footstep the piezo sensors are mounted below the platform. To generate maximum output voltage the sensors are placed in such an arrangement. This is then forwarded to our monitoring circuitry. The circuit is the microcontroller based monitoring circuit that allows users to monitor the charges and voltage a connected battery to it and this power source has many applications. It also displays the charge generated by our footstep and displays it on an LCD. Also, it consists of a USB mobile phone charging point where a user may connect cables to charge the mobile phone from the battery charge. The current is distributed using (radio-frequency identification) RFID cards so that only an authorized person can use the generator for charging.

So our proposed system senses when a user is using the seat and only then switches on the lights also allows user to operate the fan as long as user is sitting on the seats. This puts forward a method to provide automated service to train and flight travelers while at the same time avoiding any unnecessary power usage. 

User Based Device control using fingerprint sensing. We come across areas where we need to switch no device for a particular user as soon as he enters. The device could be his Pc, fan, lights etc. For this purpose we suggest a fingerprint based device switcher project. The system switches on device for a particular user automatically on sensing him through his fingerprint scan. For this we use a fingerprint scanner interfaced to a microcontroller based circuit. As soon as a person enters he/she is allowed to scan his/her finger on the scanner.On scanning the data is sent to the microcontroller, based on this data the scanned copy is now verified for authentication. If the user is verified the microcontroller switches on a device (light) to indicate as the users verification. A single device can be used for multiple functions and this rectifies the problem of having different access keys.

Now a days, Home Security threat is the most challenging task in our life. To overcome this threat, our houses must be Smart. This paper gives a solution to overcome the Home security threat. Using Zigbee network  enabled  digital  technology,  we  can  make  our home  Smart  and  secure. The  technology  gives  us the opportunity to increase the connectivity of various devices hence we can get an overall security solution. Moreover, as the area of Internet is widening, we can remotely control and monitor the network enabled devices. The device can also send signal to the remote person whom we want to notify about the threat. Common gateway is used by both the  Zigbee security  system and  Wi-Fi network  for integration purpose. The use of  this system  would be user-friendly, flexible and cost effective.   This  system  will  based  on  Zigbee  network.  Hence,  the  hardware  required  would  be  Zigbee  Modules, Micro-Controller  (ATMEGA168),  Relays, Voltage  Regulator  and various  sensor devices.  In this  method,  The sensors  will  sense  the  threat  and  send  signals  to  the  micro-controller  through  Zigbee  network  and  the micro-controller would take appropriate action and send signal to the remote location on the reception of threat signals.   Zigbee technology is simple, flexible and very reliable to use. It is broadly used transceiver standard. It has low data rate and consume low power. It’s operational range is in between 10 meters to 20 meters but can be extended upto 150 meters by the use of direct sequence spread spectrum (which is quite well for the purpose of a home).

We know that in industries, loads are distributed over large distances, At present, they are physically controlled which makes it complex to organize the lighting with the particular scene and it is not convenient to operate all those equipment time to time and it is also time to consume. For distant controlling and monitoring of different loads and by means of efficient power usage we are introducing android based programmable sequential load operation controlled system.

in this we can switch the industrial loads using programmable device and android application for sequential operation. Remote operation is achieved by any smart phone with android OS upon a GUI based touch operation.In industries, there are many tasks are carried out which requires some repeated operation in various orders and time intervals so the objective of this project is to facilitate the loads, that are to be operated either manually or automatically, by using remote Android mobile

Over the past decade, there has been drastic improvement and advancement in consumer electronics and embedded systems. Various home appliances such as light bulbs, fans, television set, CD players etc. are set to realize switching control using a coded smart phone. This has given rise to a home environment where appliances can be connected and controlled at a distance. This project demonstrates the design of an automated system to assist and provide support in order to fulfil the needs of the physically disabled and elderly ones in controlling electrical appliances in homes. The main control system implement wireless Bluetooth technology to provide remote access from our smart phones to a Bluetooth module and then to a control and switching unit. Bluetooth wireless connection enables the system to communicate with a java application on an Android smart phone without cable. The user can easily touch on the screen of the phone to control the home appliances. This portable method is able to assist the disabled, sick and elderly people who have difficulties with locomotion. This system is intended to control electrical appliances and devices in house with relatively low cost design, user friendly interface and ease of installation.

The project is designed to develop a system to detect the synchronization failure of any external supply source to the power grid on sensing the abnormalities in frequency and voltage. There are several power generation units connected to the grid such as hydel, thermal, solar etc. to supply power to the load. These generating units need to supply power according to the rules of the grid.

These rules involve maintaining a voltage variation within limits and also the frequency. If any deviation from the acceptable limit of the grid it is mandatory that the same feeder should automatically get disconnected from the grid which by effect is termed as islanding. This prevents in large scale brown out or black out of the grid power. So it is preferable to have a system which can warn the grid in advance so that alternate arrangements are kept on standby to avoid complete grid failure.

The project is designed to reduce the power loss in industries by power factor compensation through a number of shunt capacitors. The shunt capacitors will improve the power factor and reduction in amount of electrical bill for industries and commercial establishments. Reactive power is the non-working power generated by the magnetic and inductive loads, to generate magnetic flux. The increase in reactive power increases the apparent power, so the power factor also decreases. Having low power factor, the industry needs more energy to meet its demand, so the efficiency decreases. In this proposed system the time lag between the zero voltage pulse and zero current pulse duly generated by suitable operational amplifier circuits in comparator mode are fed to two interrupt pins of the microcontroller. Microcontroller displays the power loss due to the inductive load on the LCD. The program takes over to actuate appropriate number of relays at its output to bring shunt capacitors into the load circuit to get zero power loss. The 8 bit microcontroller used in the project belongs to 8051 family. Further the project can be enhanced by using thyristor control switches instead of relay control to avoid contact pitting often encountered by switching of capacitors due to high in rush current

In the upgrading countries accident is the major cause of death. If we talk about dangerous roads in the world then all of them are mountain roads and curve roads. The intensity of the deaths are more in curved roads. In the mountain roads there will be narrow roads with tight curves. In such kinds of situations the driver of a vehicle cannot see vehicles coming from other side. Because of this problem thousands of people lose their lives each year. while we are talking about mountain roads here other side might be lead to a cliff. The solution for this problem is alerting driver about the vehicle coming from other side. One of the solution is proposed in this paper. We can alert driver by placing ultrasonic sensor in one side of the road before the curve and keeping LED light other side of the curve, so that if vehicle comes from one end of the curve sensor will sense the vehicle and LED light glows at the opposite side as Red. By looking at the Red LED light driver can become alert and can slow down the speed of the vehicle. And still if an accident occurs we can save the life of victim by giving medical assistance immediately. This can increase the survival chances of victim. but this can happen only when we know the exact location of accidental place. This paper presents an inexpensive but intelligent framework that can identify and report an accident to the family member. If in case accident occurs, button will get pressed and it will send message to the family members using GSM module and send location of the accidental place using GPS module.

In this proposed petrol pump automation system, we are using RFID card to access petrol at different petrol stations of different petrol companies across the country and here, we are connecting all these petrol stations using single web server. This web server access is secured by a password which is known only to the petrol companies. Whenever we want to fill the tank from the fuel dispenser, we just have to place the RFID card near the RFID reader. Then the microcontroller reads the data from the RFID reader and performs the action according to the customer requirements. This digital petrol pump system also provides the security for the customers for filling petrol at the Petrol stations by avoiding the involvement of human beings, hence reduces the risk of carrying money every time.
