WebSep 7, 2024 · A PIR motion sensor lens detects infrared light but only quick or large changes in the field of view. The sensors usually don’t pick up on a person standing still directly in front of the lens because that’s not a change in energy levels. But if a person moves in front of the sensor, it’ll detect that because of the change in energy. WebA PIR sensor (Passive Infrared Sensor) is a type of motion sensor that detects infrared energy radiating from objects in its field of view. It is called "passive" because it doesn't emit any energy itself; rather, it senses the infrared energy emitted by objects.
