Hw-416-b Pir Sensor Datasheet [best] May 2026

While the specific model number HW-416-B appears to be a variance or specific batch code of the standard HC-SR501 PIR sensor (commonly found in Arduino starter kits), the "interesting report" regarding this device isn't a standard datasheet. Instead, the most compelling technical analysis focuses on the incredible complexity hidden inside a cheap sensor and the common myths about its potentiometers.

OUT: Digital output signal. Transitions from 0V to 3.3V when motion is detected. GND: Common ground. 4. Key Features and Operation hw-416-b pir sensor datasheet

Quick application tips

  • For door/entry use, mount at ~1.8–2.2 m height angled slightly downward.
  • For ceiling occupancy, center of room gives best uniform coverage.
  • Combine with camera or secondary sensor for verification in security systems.

Automatic Lighting: Turning on LED strips or lamps when someone enters a room and turning them off after they leave. While the specific model number HW-416-B appears to
