This project demonstrates how to measure distance using a Sharp IR sensor with an Arduino UNO. The sensor will read the distance to an object and print the value to the Serial Monitor. Connect the VCC ...

This is an Arduino example for [Grove - IR Distance Sensor](http://www.seeedstudio.com/depot/grove-ir-distance-interrupter-p-1278.html?cPath=25_31) [![Grove - IR ...

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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

Abstract: This study provides methods of measuring the distance between the human eye and an object using an infrared distance sensor. The method provides a smart way to monitor subjects near or far ...
