Parallax PIR Motion Sensor

Description 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 View more Dimensions Size: 1.41 x 1.0 x 0.8 in (35.8 x 25.4  x 20.3 cm) Operating Temp Range: 32 to 122 ºF (0 to 50 ºC) Links PDF File Manual
