Hw-416-b Pir Sensor Datasheet Updated Jun 2026

The describes a robust, adjustable, and easy‑to‑use passive infrared motion detector. Its key advantages are:

The HW-416-B lived in many projects after that: a cupboard light that only came on when hands reached in, a hallway guardian that lit the way for sleepy feet, a garden alarm that stayed quiet until a fox crossed. Each time, the datasheet—a modest document of voltages, currents, and angles—was the seed from which a practical solution sprouted.

Adjustable (typically from 0.5 seconds up to several minutes via onboard potentiometer) while True: if pir

Clockwise rotation increases the detection distance (up to ~7m), while counter-clockwise decreases it. Delay Time Potentiometer:

Below are the official and field-tested specifications for the HW-416-B. After motion, the sensor stays HIGH for the

After motion, the sensor stays HIGH for the set delay and then goes LOW, even if there is still movement.

Controls how long the OUT pin remains HIGH after motion is detected. Turn clockwise to increase the delay time (up to several minutes). Trigger Mode Jumper:
