We’re used to Hall effect devices as proximity sensors in mechanical systems ... devices provide a handy way to measure a static magnetic field. It’s something [mircemk] demonstrates, with ...

[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.

In this modern age, IR sensors are typically used in motion detectors and the best VR headsets. In the latter, they measure the depth of a space and your proximity to things in your environment.

Data encoded on magnetic stripe or proximity cards is reader by the MRC310 and passed onto a controller. The controller then makes the decision and signals back to the reader to either capture or ...
