Abstract: Automatic room lights controller can be installed in which the room lights will turn on automatically upon detection of human motion and will stay tuned until the motion stops or the person has left the room. Such type of system can be implemented where we don’t require continuous light supply but only when a person is present. The common places where we can install the system are washrooms, bathrooms, office rooms, classrooms in schools and colleges, garages, etc. Also, using this controller system, we don’t need to worry about electricity as the room lights will switch off on their own when no person is present. A huge amount of energy and economy will also be saved . The main components of the Automatic Room Lights project are Arduino Uno, PIR Sensor and the Relay Module. Keywords: Arduino Uno, Lights, PIR sensor, Relay Module
