“Passive Infrared (PIR) sensors detect motion in a local area and are the sensor of choice in security systems, home automation and proximity-sensing applications. The SparkFun OpenPIR is a highly customizable PIR sensor based around the NCS36000 PIR controller. The OpenPIR allows you to set the sensitivity, trigger time and pulse mode of the motion sensor, so you can tailor-fit it to your application.”
