I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. ... Here is the diagram of my Arduino infrared close proximity sensor ...

This type of sensor can be used to build collision avoidance systems for robots. We’ll demonstrate this sensor using a single resistor and a multimeter. Sharp GP2Y0D02 fixed 80cm IR proximity ...

Possible applications for the IR Detector proximity sensor include: – Reflective sensor for hand dryers, soap dispensers, water faucets, and toilet flush valves. – Security and pet gates.
