Introduction
In this project, we've got designed Digital Tachometer using an IR Sensor with Arduino for measuring the quantity of rotations of the rotating Motor in RPM. Simply we've interfaced the IR sensor module with Arduino and therefore the 16*2 LCD module for display. The IR sensor module consists of IR Transmitter & Receiver during a single pair that may work as a Digital Tachometer for speed measurement of any rotating object.
The tachometer is a rev counter that counts no. rotations per minute. There are two types of tachometers, one mechanical and the other digital. Here we are going to design an Arduino based digital tachometer using an IR sensor module to detect objects for the number of revolutions of any rotating body. The IR emits IR rays which are reflected back to the IR receiver and then the IR module generates an output or pulse which is detected by the Arduino controller when we press the start button. Counts continuously for 5 seconds.
