is a compact Passive Infrared (PIR) motion sensor module widely used in DIY electronics and security systems. It is essentially a variant of the popular , sharing a similar footprint and operation. Key Technical Specifications The module typically features three pins, usually labeled

The HW-416-B operates by detecting infrared radiation emitted by heat-producing bodies. When a heat source moves across the sensor's field of view, it triggers a high signal on the output pin. Specification DC 4.5V – 20V Static Current Level Output High 3.3V / Low 0V Trigger Method L (non-repeatable), H (repeatable - default) Delay Time Adjustable (approx. 0.5s to 200s) Blockade Time 2.5s (default) Detection Angle < 100° cone angle Detection Distance 3 to 7 meters (adjustable) Operating Temp -15°C to +70°C PCB Dimensions 32mm x 24mm 2.
