Arduino IR tachometer

Posted on Friday, August 31st, 2012 in Arduino, infrared, measurement by the machinegeek


Chris from Pyroelectro has posted this tutorial detailing the use of an IR transmitter and receiver break-beam pair to measure the speed of a fan. The IR components are used in conjunction with the Arduino UNO which processes the break-beam interruption counting with the result displayed on a 16×2 LCD display.

You can get the details on this project, along with schematic and Arduino code at Chris’ Pyroelectro website.
