The PIR Sensor detects motion up to 20 feet away by using a Fresnel lens and infrared-sensitive element to
detect changing patterns of passive infrared emitted by objects in its vicinity. Inexpensive and easy to use, it's ideal
for alarm systems, motion-activated lighting, holiday props, and robotics applications. The PIR Sensor is compatible
with all Parallax microcontrollers; sample BS1, BS2, and SX/B programs and product documentation are available
under Downloads (coming soon!).
