Automatic Room Light ON/OFF Control using Arduino

Abstract

The concept and construction of an automatic room light ON/OFF control utilising an Arduino and a PIR sensor are presented in this research article. When a person enters the room, the system is programmed to turn on the lights, and when the room is empty, it is programmed to turn them off. The device uses a Passive Infrared (PIR) sensor and an Arduino microcontroller to detect the presence of a human in space. The relay is then managed by the microprocessor, and it manages the lighting. This paper describes the configuration of
the conveyor that is mounted on the motor shaft. This paper describes the configuration of the conveyor that is mounted on the motor shaft. The conveyor turned due to the motor's rotation. Water debris, trash, and
plastics are gathered from water bodies as the conveyor moves, are hauled higher, and are then placed onto a
tray. The machine is propelled by a propeller with the aid of a PMDC motor. the remote machine control
system's RF transmitter and receiver. It rotated at a specific angle to collect the waste for the model using this
four-bar system.
