[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. 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 ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and ...

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a ...

The big picture: If you don't know anything about electronics but have always wanted to learn and build your own IoT project, Arduino has the solution for you. The Plug and Make Kit is a comprehensive ...

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 ...

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 ...

[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 ...
