This project refers to an Arduino sketch that implements a motion detector for driving and controlling other devices using a passive infrared sensor (PIR) and an electromechanical switch (relay). The program examines whether there is movement (the detection range of the detector is about 6 meters) in space (via the sensor PIR) to activate the device via the relay.
Possible applications:
- Use for automatic switching on / off of a lamp
- Use for automatic opening / closing of a door
- Use for alarm triggered by motion
Below is a picture of the project:

Of course, I can help you!
Either through email or you can find me at TheHackerspace in Kalamaria!
Be well!
Hi Efstathios, bravo for your project; I have found many interesting things in here.. I am a student at the Technological Educational Institute of Kavala and in one lesson we have undertaken to do a job for automatic door openers. We chose to do it with Arduino and PIR sensor so that as soon as the sensor detects movement to move the motor but we have stuck. I saw that you have implemented it. Perhaps you could help us a little? We’ll be grateful.
