The PIR sensor is highly effective for motion detection in the lighting systems considering the power consumption and efficiency. Because of its low power usage, it can be used in devices powered by batteries. This sensor utilizes passive infrared technology which captures the heat emitted by moving objects, therefore providing motion detection that is dependable and precise. Most importantly, reduced power consumption extends battery life and decreases the rate at which the battery needs to be changed. For residential and commercial purposes, the PIR sensor provides a cost-efficient and energy-efficient solution for operating lights activated by motion and powered by batteries.
