[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 ...

Hello everyone! Today I’m going to discuss a cheap type of useful digital rotation per minute counter (Digital RPM Counter). The 4-Digit LED Display RPM comes with a magnetic proximity sensor switch.

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...
