[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 ...

A lot of new cars have fancy cameras on the rear bumper to help you parallel park. If your car doesn't have that feature, DIY blog Mad Science has put together a tutorial to roll your own sensor ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

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.

[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 ...
