PIR sensors can directly interface with microcontroller I/O pins for motion activated control. Here is an exampleArduinosketch for a basic motion detector: const byte pirPin = 3;// PIR connected to pin 3void setup(){ pinMode(pirPin, INPUT);// Set pin as inputSerial.begin(9600);// Star...
PIR Sensor Most PIR sensors have a 3-pin connection at the side or bottom. One pin will be ground, another will be signal and the last pin will be power. Power is usually up to 5V. Sometimes bigger modules don’t have direct output and instead just operate a relay which case there i...

More advanced security systems includepassive infrared(PIR) motion detectors. These sensors "see" the infrared energy emitted by an intruder's body heat. When an intruder walks into the field of view of the detector, the sensor detects a sharp increase in infrared energy. Of course, there will...
