[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 camera’s image sensor is one of the most important pieces of tech to capture images. It’s the small element deep inside your camera that converts light waves into electronic signals that actually ...

German engineer Gaurav Singh has designed and built an industrial USB box camera in a custom 3D-printed case that not only accepts interchangeable lenses, but the image sensor can also be swapped out ...

Nanoengineers from the University of California, San Diego are making it possible for anyone to build sensors at any time with high-tech bio-inks that react with several chemicals, including glucose.

Until recently, measuring air pollution was a task that could be performed only by trained scientists using very sophisticated – and very expensive – equipment. That has changed with the rapid growth ...
