Parallax Inc PIR Sensor Module / 8430840

PIR sensor module (Wide-angle). The PIR (Passive Infra-Red) 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. This logic signal can be read by a microcontroller or used to drive an external load. This particular device has a large detection angle of 180°. 180˚ detection angle for wide area motion detection Typically detects people up to 10m away User-selectable "night-time mode" for detection after dark only Adjustable sensitivity Output: logic high = movement detected Movement detected LED Optimised for IR wavelength range: 5500 to 14000nm Power supply: +3.0 to +6.0Vdc @ 3mA Idle current: 150uA Dimensions: 36 x 36 x 20.2mm Operating temperature range: 0 to +50°C
