Project Overview 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 ...

arduino-mega-distance-sharp-ir-sensor The Arduino Mega interfaces with a Sharp IR distance sensor module, allowing precise measurement of distances based on infrared reflection, suitable for robotics, ...

The Sharp sensor is cheap and decent, but you’re obviously not going to get amazing accuracy. Still, using the average of several measurements, he ends up with a decent result.
