Abstract For Digital Tachometer

A rotating object may be a bike tire a car tire or a ceiling fan or any other motor and so on. A tachometer is an electromagnetic device that produces an analog voltage that is proportional to motor speed. It is built using a microcontroller an alpha numeric lcd module and an infrared system to detect the rotation of the fan whose speed is being measured.

A digital tachometer circuit comprises lcd or led readout and a memory for storage.

Abstract for digital tachometer. Abstract a microcontroller based tachometer is a device that measures the rotation speed of a shaft or disk in motor or other machines. In the past most servo systems relied on tachs for velocity feedback. Here we design a tachometer which performs the same operation as above. A digital tachometer is a digital device that measures and indicates the speed of a rotating object.

Abstract a tachometer with digital indication was built for measuring the speed of automobile engines with only two digits in the rpm readout. Abstract basically a tachometer is one which shows the speed of a rotating part in rpm which may be either the inputoutput of a motor or moving wheel or shaft etc. This device is an embedded system. Tachometers or tachs provide highly resolved low phase lag velocity signals that are ideal for closing velocity loops.

A digital tachometer for determining and displaying the speed of rotation of a rotating device by counting pulses derived from an electrical sensor signal produced by a sensor sensitive to the.
