PIR Motion Detector Sensor Switch micro controller compatible, or as Stand-Alone Motion Switch. The passive infrared sensor measures that little amount of infrared radiation coming for example from living object or running engines. The high-time after activating can be adjusted by replacing a chip resistor, and it set to 2.5s by factory default. The maximum detection distance is about 5m, but not more are 3.5m are recommended for reliable operation. The output pin can drive simple loads like transistors or GPIO ports.
Operating Voltage: 3.3 – 15V Quiescent current: 20µA Dimensions: 16 x 13 mm Weight: 2.1g
