The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

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 ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...

The MyoWare muscle sensor project is currently over on the Kickstarter crowd funding website looking to raise $10,000 in pledges to make the jump from concept to production. So if you think the ...

This project is to prototype a set of self-powered (such as piezoelectric, thermostat, solar, etc) embedded sensor systems for pervasive computing. A tangible exam is a body-temperature powered motion ...

In this project, students will design and prototype a novel wearable sensor for continuous physiological monitoring (e.g., heart rate, blood pressure, glucose, etc.). Besides the conventional ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the… ...
