Hw-416-b Pir Sensor Datasheet -

The HW-416-B uses a simple three-pin interface (VCC, OUT, GND), but also features a four-pin configuration header that allows advanced options.

Unlike active sensors that emit a signal (like ultrasound or radar), the HW-416-B is passive. It only listens for changes in the ambient infrared spectrum. The module integrates a pyroelectric sensor element, a specialized control chip (frequently the BISS0001 or a similar ASIC), a Fresnel lens to focus incoming light, and supportive passive components on a single printed circuit board (PCB). 2.
