How PIRs Work | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

Arduino - PIR Sensor - Tutorialspoint

PIR sensor has three terminals - V cc, OUT and GND. Connect the sensor as follows −. Connect the +V cc to +5v on Arduino board. Connect OUT to digital pin 2 on Arduino board. Connect GND with GND on Arduino. You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor board.

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.

PIR Sensor Circuit and Working with Applications

PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output. It is very simple and easy to interface the sensor with a microcontroller. The output of the PIR is (usually digital output) either low or high.
