All objects emit energy in the form of invisible infrared radiation. A passive infrared (PIR) sensor detects movement of infrared-emitting sources within its field of view. This allows it to sense when an animal passes in front. The term “passive” refers to the fact that the sensor does not emit radiation but instead monitors the levels if infrared radiation falling on it. As a result, PIR sensors are very energy-efficient .

I am an enthusiastic amateur photographer with a big passion for photography who loves to take pictures. I’m always aiming to learn new photographic skills and would like to spend more time out in the field or on a photo shoot with my camera.
