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
