The light source and light sensor are co-packaged (except for units designed for through-beam use), and the electrical connections are basic power, output signal, and ground. Figure 1. A basic optical ...

[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.

We propose a method for simultaneous articulated robot posture estimation and environmental mapping by integrating data from proximity sensors distributed over the whole body. Our method extends the ...
