The HW416B is a passive infrared sensor module designed for human body detection. It is widely used in security systems, automatic doors, and lighting control applications. The sensor is highly sensitive, reliable, and easy to use. The HW416B has no reverse polarity protection on many clones
The HW-416B features two orange trim pots (potentiometers) on the back. Knowing how to turn them is the difference between a working project and a false-trigger nightmare. PIR (motion) sensor - Adafruit
