A novel direction measurement signal conditioning circuitry: article / Wan Norhayati Wan Gati

This paper presents an approach in signal conditioning circuitry design for direction measurement. The goal of this project is to achieve an accurate measurement of the direction using a photodiode as a transducer. A signal conditioning circuitry is used to transform the input signal from a sensor into a suitable output in terms of degree (°). The reflection of light is captured by a photodiode when the slotted disc rotated. The slotted disc has different depth at every corner. The signals captured at every depth and then transformed to the desired output.
