Automatic Room lights Control by Using Arduino and IR

It can be used to turn ON and OFF the lighting system of the home automatically by detecting the presence of humans. This system can be used in garages, classrooms, staircases, bathrooms, etc. where there is no need for continuous light but only when there is a human. Also, there is no need to worry about electricity bills as the lights get OFF when there is no human and hence one needs to pay the bills as peruse. The main components used in this system are Arduino Uno, PIR, and Relay Module. Out of these components, the operation of the system mainly depends on the PIR sensor which helps in detecting human presence.
