PIR Sensors Info

Pyroelectric devices, such as the PIR sensor, have elements made of a crystalline material that generates 
an electric charge when exposed to infrared radiation.  The changes in the amount of infrared striking the 
element change the voltages generated, which are measured by an on-board amplifier.  The device 
contains a special filter called a Fresnel lens, which focuses the infrared signals onto the element. As the 
ambient infrared signals change rapidly, the on-board amplifier trips the output to indicate motion.

PIR Motion Sensor Circuit Boards

Hundreds of circuit boards incorporating PIR motion sensors were donated to Noisebridge. They are available for use immediately, and they are currently located in the storage area of the 83c Mezzanine.

Brainstorm ideas for projects incorporating this large number of boards and sensors.
