What it does

The PIR Motion Detector Sensor Module for Arduino, Raspberry Pi & IoT Projects detects motion by sensing changes in infrared radiation from warm bodies. An essential component for security systems, automatic lighting, and occupancy detection projects.

Key features

  • Passive infrared detection with pyroelectric sensor
  • Adjustable sensitivity via potentiometer (up to 7 meters)
  • Adjustable delay time via potentiometer (5-200 seconds)
  • Low power consumption ideal for battery projects
  • Digital output (HIGH/LOW) for easy interfacing
  • Wide detection angle of approximately 120°
  • Repeatable and non-repeatable trigger modes

Good to know

  • Allow 1 minute warm-up time after power-on for stable operation
  • Avoid pointing toward direct sunlight or heat sources
  • Sensitivity decreases in high ambient temperatures
  • Lens cap color (white) affects detection range slightly
  • Do not cover or obstruct the dome-shaped Fresnel lens
