How PIR Sensors Work and Their Application in Different Lighting Conditions
How PIR Sensors Work and Their Application Passive Infrared (PIR) sensors are widely used in various applications, from security systems to automatic lighting control. These sensors operate based on detecting changes in infrared radiation emitted by objects within their field of view. Unlike some other types of sensors, PIR sensors are not affected by visible light, making them effective in both light and dark environments. Here we will see how PIR sensors function and their…
