The HW416B is a motion detector module based on the passive infrared principle. It senses changes in infrared radiation—specifically, the heat signature of a moving human or animal. Unlike its cousin the HC-SR501, the HW416B is often marketed as a , though specifications vary wildly between sellers. hw416b pir sensor datasheet better
