Parallax PIR Sensor with LED Signal

This PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the build-in LED lights up the lens dome as a visual signal, and the module also outputs a high signal on its output pin. This is the latest revision B version of this sensor, which includes the following improvements:

* Longer detection range, selectable by an 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

Check out the product guide for more information. 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

* 3-pin SIP package perfect for breadboard-friendly projects

* Easy communication with any microcontroller

* Small size makes it easy to conceal
