Motion Sensor: PIR Sensor (Passive Infared Sensor)

PIR Sensor Module


  • To detect moving human body in specific area.
  • Combined with fresnel lens

Specification:
  • Supply current DC of 5V
  • Voltage output: High/Low of 3.3V
  • TTL Output
  • With high sensitivity
  • Delay time about 5s - 18minutes
  • Operating temperature from 15 degree to 70 degree Celcius
  • Infrared sensor: dual element
  • Operating range: 5m to 7m
  • 3 pins: Vcc, Out, and Gnd

IIUM Smart Room will be using this sensor to detect the presence of moving human body. Though our design are using multiple PIR sensors but for the sake of prototype, we will only use one sensor to demonstrate the outcome of the project.

*Specification based on PIR Sensor
