In our project ,we will try to find a solution to the power consumption especially at universities, schools and academic institutes.
If any person enters the room , the PIR sensor will activate and sense the heat of the person .The PIR sensor will sends signal to the microcontroller that someone is inside because the infrared level at the sensor will increase. Microcontroller after receiving the signal from PIR sensor will control power switch .If lights and AC unit are off, so they will be turned on, but projectors will stay off because they are not always used by teachers. When people leave the room , the level of infrared energy at the sensor will decrease giving a signal to the microcontroller to switch off the light and the AC unit. At the same time a signal will be sent to the projector to turn off. The circuit will be designed so as the projector will be turned off only automatically.
