A Digital RPM Meter is a measuring instrument which can measure the rotational speed of a rotary machine digitally.In industries we can use this type of digital tachometers which will reduce human effect.The industrial name of this instrument is "Tachometer".It is an important measuring device in the field of electrical engineering & widely used in industries and laboratorial work.Here we are going to design an Aurdino based digital tachometer using IR sensor module to detect object for count rotation of any rotating body and the programming is given by the FTDI programmer.As IR transmits IR rays which reflect back to IR receiver and then IR Module generates an output or pulse which is detected by the aurdino controller when we press start button.It counts continuously for 5 seconds.After 5 seconds aurdino calculate RPM for a minute using given formula.Here we demonstrate this project using ceiling fan.
