What is a PIR sensor?
PIR (“passive infrared”, “pyroelectric” or “infrared motion”) sensors are used as motion sensors. They can determine whether a human being (and in the case of the Adafruit PIR sensor, an animal) has entered or left the module’s detection area.
Strong, cheap and ultra-compact, these small sensors are frequently used not only to design small electronic objects and gadgets making use of motion detection, but also for prototyping.
PIR Motion Sensor by Adafruit: practical and adaptable
Like all PIR sensors, this motion sensor module designed by Adafruit is extremely easy to use and pretty energy efficient. Better still, it offers a certain flexibility since you can:
- decrease its power requirements and pass from 5 to 3V (with a few soldering operations to bypass the regulator);
- adjust the motion sensor’s response time (between 2 and 4 seconds);
- adjust the module’s sensitivity; and
- position your sensor as you want thanks to the 30 cm cable with socket also supplied with the PIR sensor.
