Burglar Alarm using PIR sensor - Arduino Project Hub

PIR sensor is a special type sensor which is usually used for security purposes. It detects the objects by reading the Infrared radiations emitted by the objects. Any object whose temperature is above absolute zero, emits radiation. This radiation is not visible to human eyes. The PIR sensor is designed to detect this Infrared radiation.

Arduino - PIR Sensor - Tutorialspoint

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. Once the sensor detects any motion, Arduino will send a message via the serial port to say that a motion is detected.

Arduino – (Very) Basic motion tracking with 2 PIR sensors

· PIR Motion Sensor Arduino Code. This isn’t too bad. Basically we set 2 sensors and have a few if statements to do shit based on if they turn on or off, so essentially they’re treated just like a couple of switches. /* - 2 3pin PIR sensors to track basic motion. We have 1 sensor for left, 1 for right. The left sensor is triggered, the LED for the left comes on and the servo ...
