HW-416-B PIR Sensor Datasheet

1. Overview

The HW-416-B is a passive infrared (PIR) motion sensor module based on the HC-SR501 design. It detects changes in infrared radiation (body heat) within its field of view. It is widely used for human/animal motion detection in security systems, automatic lighting, and IoT projects.

modules include a jumper to switch between two trigger modes: Non-Repeatable Trigger (L): hw-416-b pir sensor datasheet

HW-416-B Pinout Configuration

Unlike the HC-SR501, which often has a 3-pin header, the HW-416-B typically exposes three pins labeled on the back of the PCB: HW-416-B PIR Sensor Datasheet 1

void loop() int motionState = digitalRead(pirPin); False Triggers : Adjust sensitivity and delay time

uses internal digital signal processing which makes it less susceptible to power supply noise or electromagnetic interference.
