PIR SENSOR BY PARALLAX

The PIR (Passive Infra-Red) Sensor 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.

Features:
Detection range up to 15 ft away on short setting, up to 30 ft away on long setting
Jumper selects short or long settings
Directly drive a load
Onboard LEDs light up the lens for fast visual feedback when movement is detected
Mounting holes for 2-56 sized screws
3-pin SIP header ready for breadboard or through-hole projects
Small size makes it easy to conceal
Easy interface to any microcontroller

Application Ideas:
Motion-activated nightlight
Alarm systems
Holiday animated props
