Passive Infrared Motion Sensor

The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR sensor outputs a high signal on its output pin.

Key features:

  • Typically detects a person up to approximately 30 feet away, or up to 15 feet away in reduced sensitivity mode
  • Jumper selects normal operation or reduced sensitivity
  • Approximately 90 degree field of view
    Onboard LEDs light up the lens for fast visual feedback when movement is detected
  • Mounting holes for 2-56 sized screws provide easy integration in permanent applications
  • 3-pin SIP package perfect for breadboard-friendly projects
  • Easy communication with any microcontroller
  • Small size makes it easy to conceal
