Hw-416-b Pir Sensor Datasheet ✧

Avoid placing the sensor near heat sources, air conditioners, heaters, or direct sunlight. Moving air currents with distinct temperatures can trip the sensor.

While exact mechanical drawings vary slightly by manufacturer, typical dimensions for the HW-416 module are approximately with a height of roughly 25 mm when accounting for the lens and potentiometers. Allow for an additional ~10 mm clearance when planning enclosure space.

If you are searching for the official , you may have noticed that a unified manufacturer datasheet is hard to find. This is because the HW-416-B is a generic module design produced by several OEMs. To solve this, this article aggregates verified technical specifications, pinout definitions, timing diagrams, and calibration instructions to serve as the definitive reference for the HW-416-B.
