Create interesting and compact devices to use in work and home using the Motion Sensor Board. This add-on board includes a passive infrared type movement sensor AMN11112, which detects changes in infrared spectrum when a person or object moves. This motion sensor features quad-type pyroelectric element, which makes it an ideal choice for small-movement detection applications. The sensor is protected with a plastic cap, which includes miniature lenses in order to boost sensor precision. In case some changes are detected in the infrared rays, the microcontroller.
