Passive IR (PIR) sensor modules provide motion detection and control to smart home and building systems.

IR sensors are commonly used for object detection, distance measurement, motion sensing, and proximity applications. They operate either in active mode, where they emit IR light and detect reflections ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object ...
