[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.
This project contains the definition of an Arduino library for the VCNL4000 sensor. This sensor is able to perform relatively short (< 7 inches) proximity sensing and light intensity readings. The ...

This light and proximity sensor has a 0x44 fixed I2C address. If multiple sensors need to be used, an I2C mux or translator is needed. Download the .zip file from Github, in Arduino go to Sketch -> ...
Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very simple to build. All you need are a few basic parts, ...
