Hw-416-b: Pir Sensor Datasheet

The HW-416-B supports both repeatable and non-repeatable trigger modes via its jumper. If the sensor is not retriggering during continuous motion, ensure the jumper is set to (Repeatable) mode.

| Pin name | Function | | :--- | :--- | | | Power supply (5 V typical) | | OUT | Digital output (HIGH when motion is detected) | | GND | Ground |

Most cheap PIR sensors are designed to run on 5 V, and the HW‑416‑B is no exception. However, its internal electronics actually operate at 3 V, and the module includes a voltage regulator to handle a range of input voltages.

This makes coding incredibly simple. You don't need complex analog-to-digital conversion; you simply check if a digital pin is HIGH. If it is, sound the alarm.

Digital output pin. Outputs 3.3V (HIGH) when motion is detected and 0V (LOW) during standby. GND: Ground connection. Connect to the system ground.

When using a Raspberry Pi with the RPi.GPIO library, the wiring is the same and the code is straightforward:
