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 ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

The vibrating proximity sensor is an amazing infrared proximity detector device that scans a limited area in front of it. When it detects the close proximity of an object within its field of view, a ...
