This detector circuit uses just the Arduino Nano itself, no added sensor. Blowing some air from 30cm distance can be detected. It detects via measuring the internal heated chip temperature with 0.01 ...

This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ideal for simple security systems or motion-based ...

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

This project uses an Arduino, joystick, servo motor, LCD display, buzzer, red and blue LEDs to monitor joystick activity and detect prolonged inactivity. The system starts in Safe Mode, where: The ...

infra-red movement detector elektor June 1985 The detector described in this article reacts to fast temperature variations caused by the movement of people or animals in an enclosed space. All mammals ...

If you have an upcoming long distance move and you're concerned about thieves breaking into your moving truck you can rig up a motion alarm system that will send a text message as well as trigger an ...

Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino in ...
