PIR Sensor with LED Signal - Parallax

The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected a LED lights up the lens dome as a visual signal, and the module also outputs a high signal on its output pin. NOTE: The product information found on this page currently pertains to Revision B of this product ...

Overview | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· Along with the pyroelectic sensor is a bunch of supporting circuitry, resistors and capacitors. It seems that most small hobbyist sensors use the BISS0001 ("Micro Power PIR Motion Detector IC"), undoubtedly a very inexpensive chip takes the output of the sensor and does some minor processing on it to emit a digital output pulse from the analog sensor.
