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 ...

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 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 ...

[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

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 ...

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 ...

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 ...
