In this Arduino metal detector project we are going to use a coil and capacitor which will be responsible for the detection of metals.

This active IR sensor module is perfect for obstacle avoidance robots, motion detection systems, and proximity sensing applications. Whether you're building your first Arduino project or need a ...

Everyone has had something in their home or workplace fridge go missing, and now a do-it-yourself lie detector may help locate the culprit. A USB polygraph was created by a maker and powered by an ...

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 ...

The TMD2671 is a digital proximity detector that includes an integrated LED driver and IR LED.The proximity detector in this device operates from sunlight to dark rooms and is calibrated to 100-mm.The ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
