PIR Sensor (Rev B)

The PIR (Passive Infra-Red) Sensor is a pyroelectric device that 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. This logic signal can be read by a microcontroller or used to drive an external load. Dual output modes and a sensible design that performs within stated datasheet specifications are a few reasons over 100,000 units are in use around the world. Click over to the KickStart Guide to see how to use the PIR sensor, complete with wiring diagrams and sample code for the BASIC Stamp, Propeller, and Arduino. You might also like the Wide Angle PIR sensor (P/N: 2205018)
