Overview

The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected a LED lights up the lens dome as a visual signal, and the module also outputs a high signal on its output pin.

NOTE: The product information found on this page currently pertains to Revision B of this product, which provides many updates and features from Revision A. Some of these include:

  • Longer detection range, selectable by onboard jumper
  • Wider supply voltage, from 3 to 6 VDC
  • Higher output current provides for direct control of an external load
  • Mounting holes included for permanent projects
  • All parts SMT

Key Features:

  • Typically detects a person up to approximately 30 ft away, or up to 15 ft away in reduced sensitivity mode
  • Jumper selects normal operation or reduced sensitivity
  • Approximately 90 degree field of view
  • LEDs light up the dome for visual signal of sensor activation  
  • Mounting holes for 2-56 sized screws provide easy integration in permanent applications
