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.This chip takes the output of the sensor and does some minor processing on it to emit a digital output pulse from the analog sensor.

Passive infrared sensor - Wikipedia

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved.

Sensor PIR / Sensor Movimento para Arduino

O Sensor PIR consegue detetar o movimento de objetos que estejam numa área de até 7 metros! Caso alguém se movimentar nessa área o pino de alarme é ativado. É importante referir também que este sensor deteta somente movimento e não presença, isto é, se algo permanecer parado a frente dele, o sensor PIR não deteta.
