A simple velocity measurement signal conditioning circuit: article / Heldinna Nyotem

This paper presents an approach in signal conditioning circuit design for velocity measurement. The goal of this project is to achieve an accurate measurement of the velocity using a rotational disc and a photodetector as a sensor. A signal conditioning circuitry is used to transform the input signal into a suitable output. The light from the light source is captured by a photodetector when the disc rotated. The signals captured are then transformed to the desired output that is in term of frequency, voltage and speed in meter per second.
