The is a highly popular, low-cost Passive Infrared (PIR) motion sensor module , frequently identified as a variant of the widely used HC-SR501 . It is a "passive" device, meaning it does not emit energy but instead detects changes in infrared radiation (heat) emitted by humans or animals moving within its field of view. Technical Specifications Users recommend mounting the sensor at least 2

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
