Digital Tachometer using IR Sensor with Arduino


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.

Components Required

1. Arduino uno
2. 16*2 LCD 
3. IR module
4. Bread board
5. Jumper wire as per connection 
6. Arduino usb cable

full connection of DIY techometer

Now after managing these components make the following connections to design a digital tachometer using IR sensor with Arduino to measure rpm

THIS IS FOR 16X2 LCD DISPLAY  CONNECTION WITH  I2C MODULE

GND - GND
VCC - 5V
SOA - A5 
SCL - A4

                                           NOW IR SENSOIR CONNECTION  



GND - GND 
Signal pin - D2
VCC - 5v 

Now you can copy our code and paste it in your arduino IDE
   
This code will be working 100%  so you can enjoy your project thank you
