PIR (Passive Infrared) sensors use variations in the infrared light that objects release to identify motion. They are widely used in automatic lighting, occupancy detection, and security systems to enhance convenience, safety, and energy efficiency. They also activate lights, set off alarms, and optimize energy usage based on occupancy levels. In this lesson i used the sensors to detect the lighting in my room and a flashlight to test its capability’s.
