1. Overview The HW-416-B is a passive infrared (PIR) motion sensor module commonly used in Arduino, Raspberry Pi, ESP32, and other microcontroller projects. It is functionally similar to the popular HC-SR501 but features a different PCB layout, lens, and sometimes a smaller form factor. The module detects infrared radiation emitted by moving humans or animals within its field of view. 2. Key Specifications (Based on Typical Datasheet) | Parameter | Value / Range | |-----------|----------------| | Operating Voltage | 5V – 12V DC (typically 5V) | | Quiescent Current | < 50 µA (standby) | | Active Current | < 1 mA (during detection) | | Detection Range | Up to 7 meters (adjustable) | | Detection Angle | ≤ 110° (with standard Fresnel lens) | | Output Signal | High (3.3V) / Low (0V) digital output | | Output Hold Time | 0.5s – 200s (adjustable via potentiometer) | | Trigger Modes | Single trigger (L) / Repeatable trigger (H) | | Warm-up Time | 30 – 60 seconds after power-up | | Operating Temperature | -20°C to +80°C | | Dimensions | ~32mm x 24mm x 24mm (excluding lens height) | 3. Pinout The HW-416-B typically has three pins : hw-416-b pir sensor datasheet

For precise design, always verify the actual silkscreen markings on your module and consult the BISS0001 IC datasheet for internal operation details.
