Abstract :
The measurement of instantaneous torque in
terms of voltage displaying rotating speed in revolution per
minute (RPM) of a rotating shaft is known as a digital
tachometer. An infrared module is used as the input that
senses the interruption in terms of beam of rays caused by
rotating shaft, generating a pulse. The usual method of
counting pulse coming from the encoder in a fixed period
of time produces a high precision velocity estimate in the
high-speed range. The encoded signal is latched and
further sent to decoder that decodes the latched pulse i.e.
speed displayed in 7 segment display. This paper mainly
focuses on developing a contact-less digital tachometer of
maximum 3digit with the help of integrated circuits (ICs).
