The objective of this project is to control and save the energy by using 8051 micro controller. By using the IR Sensors at the entrance and exit we can detect the number of people inside the room. For temperature monitoring temperature sensor is used.
As the number of people entering in to the room increases, the temperature also increases then turn ON lights increases. similarly if the number of people living from the room then temperature decreases then there is no turn ON lights. It is called as automatic switching devices based temperature sensor.
In this device we continuously monitor the IR Sensors by using the AT89C51 controller.
