Parallax PIR Motion Sensor

• Longer detection range, selectable by onboard jumper
• Wider supply voltage, from 3 to 6 VDC
• Easy interface to any microcontroller
• Small size makes it easy to conceal

The Parallax PIR Motion 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.

Features

• Detect a person up to - 30 ft. away, or up to 15 ft. away in reduced sensitivity mode
• Jumper selects normal operation or reduced sensitivity
• Source current up to 12 mA @ 3 V, 23 mA @ 5 V
• Mounting holes for 2-56 sized screws
• 3-pin SIP header ready for breadboard or through-hole projects
