Hw-416-b - Pir Sensor Datasheet Upd

The HW-416-B features a highly intuitive hardware layout, typically consisting of a 3-pin interface for connectivity, two potentiometers for manual tuning, and a jumper configuration for trigger selection. Pin Configuration

Digital output pin. Outputs 3.3V Logic High when motion is detected, and 0V Logic Low when idle. GND: Ground connection. 🛠️ On-Board Controls and Adjustments

Increases sensitivity (detects motion further away, up to 7m). hw-416-b pir sensor datasheet

The HW-416-B uses a simple three-pin interface for basic operation:

For a 3.3V logic system (like an ESP32), you can power the module using the dedicated 3.3V configuration pin instead of the standard 5V input, as described in the previous section. The HW-416-B features a highly intuitive hardware layout,

Increases the duration the output remains HIGH after motion stops (up to 200s+). Counter-clockwise: Decreases the delay (down to ~0.5s). Trigger Mode Jumper (L/H)

Users have reported some common issues, particularly with false triggers or the sensor not behaving properly. GND: Ground connection

: Controls how long the "High" signal persists after motion is detected.
