To use the HW-416-B with an Arduino Uno or similar 5V logic board: hw-416-b pir sensor datasheet

PIR sensors are highly sensitive to rapid environmental changes. Avoid mounting the HW-416-B directly facing windows, heating vents, air conditioners, or high-power incandescent lighting, as sudden shifts in air temperature can falsely trip the sensor.

The module typically features three pins, which are often labeled on the board under the white Fresnel lens. Power input (Positive). Digital output signal (High when motion is detected). Ground (Negative). Adjustment Potentiometers Functionally identical; only PCB layout and color differ

Detection Range: 3 to 7 meters (Adjustable). Detection Angle: Approximately 110° to 120° cone. Operating Temperature: -15°C to +70°C. 🛠️ Tuning the Hardware

This guide serves as a functional datasheet and implementation manual for engineers and hobbyists alike. 1. Technical Specifications The module typically features three pins, which are

Below are the official and field-tested specifications for the HW-416-B.

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:

Because of its low power consumption, the HW-416-B is perfectly suited for modern automation workflows:
