So, with just two cheap modules, you can build a laser proximity sensor—whether it is the thru-beam type or the reflective type. But I will not go into the build ideas as there are countless tutorials ...

This flat-pack proximity sensor tells a controller that the die has closed properly. ... and maintenance. According to Turck Inc. in Plymouth, Minn., only a few stamping companies use this service.

[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 … ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators. Most determine direction of rotation, speed, and angular ...
