Overview | PIR Motion Sensor | Adafruit Learning System

2014-01-28· 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.

PIR Sensor Based Motion Detector / Sensor Circuit Diagram

2015-05-22· PIR Sensor Based Simple Motion Detector/Sensor Passive Infrared Sensor (PIR) is very useful module, used to build many kinds of Security Alarm Systems and Motion Detectors. It is called passive because it receives infrared, not emits. Basically PIR sensor detects any change in heat, and whenever it detects any change, its output PIN becomes HIGH.

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

2014-01-28· When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected.

2015-02-09· Not all PIR sensors have the same output or even output type. A pull-up resistor is needed when the output type is what's known as a "open collector" (or open drain). These type outputs use a transistor (or a FET) to produce a short circuit to ground, generally when the PIR detects something. When there's no detection, then the transistor is an open circuit and that leaves the Arduino input ...
