To measure how fast something spins, most of us will reach for a tachometer without thinking much about how it works. Tachometers are often found in cars to measure engine RPM, but handheld units can ...
It’s often necessary to measure a motor’s rotational speed without any physical contact with the motor or its shaft. Some methods use a mirror attached to the motor’s rotating part to reflect a pulsed ...
The project describes the construction of a contact-less tachometer by using a 8051 microcontroller and a proximity sensor to be used in counting the revolutions per minute of a rotating shaft. The ...
