PIR Motion Sensor

This is a simple to use passive infrared (PIR) motion sensor with 4-position 2mm header (JST B4B-PH-K-S). Connect it to your Arduino with a 20cm 4-pin cable (5 pack, sold separately) and upload your code and when something moves in its detecting range, the sensor outputs HIGH on the SIG pin.

The detecting range and response speed can be adjusted by two potentiometers soldered on the circuit board. The response time is from 0.3s - 25s, and max 6 meters of detecting range.

Specifications

  • Voltage range: 3V-5V
  • Operating Current @ 3V: 100µA
  • Operating Current @ 5V: 150µA
  • 2.0cm x 4.0cm
  • Detecting angle: 120 degree
  • Measuring Range: 0.3 inches to 19.5 ft.
  • Detecting distance: 6m (19.5 feet) max
  • Holding Time: 1 - 25s
  • Adjustable detecting distance and holding time
  • Working Wavelength: 7 - 14µm

Application Ideas

  • Motion sensor
  • Thief-guarding System
  • Switch
  • Industrial automation

Wiring

  • On-board socket header: JST B4B-PH-K-S
  • Compatible mating connector: JST PHR-4
  • GND = Ground
  • VCC = 5V
  • SIG = Digital pin 2 (based on sample code (.zip))
  • Delay time potentiometer = 25s to 1s when rotated clockwise
  • Distance potentiometer = 19' to 5" when rotated clockwise
