[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 ...

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

In order to find the dynamic TDC a microwave sensor was installed on the head and a proximity probe on the wall of 4-cyl SI engines. The dynamic TDC determined by the microwave system exhibited fairly ...

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.
