Abstract - In this project, the Automatic Room Lights using
Arduino and PIR Sensor, where the lights in the room will switch on and off automatically when a human enters the room is made. Such Automatic Room Lights can be installed in garages, stairwells, restrooms, and other areas where we do not want continuous lighting but just when we are present. Also, with the help of an automatic room light control system, you won't have to worry about running out of electricity because the lights will turn off automatically when no one is in the room. So, in this DIY project, we used Arduino and a PIR Sensor to construct Automatic Room Lights. Key Words: Automatic Room Lights, Arduino and a PIR Sensor.
1. OVERVIEW The Automatic Room Lights System with Arduino is a highly handy project since it eliminates the need to turn on and off switches every time you want to turn on the lights. The Arduino, PIR Sensor, and Relay Module are the primary components of the Automatic Room Lights project.
The PIR Sensor is the focal point of the three components because it is the primary device for detecting humans and human motion. In reality, the Automatic Room Lights project is a key use of the PIR Sensor. A comparable principle is already in use in automatic toilet flush valves, hand dryers, and other products Components Used in this project :
Arduino UNO
PIR Sensor
Breadboard
Relay 5V
LDR – Light Dependent Resistor (photodiode )
Resistor
Bulb
Power Supply
