Photoelectric Speed Sensor Encoder

Overview

One side of the optical sensor holds a light emitting diode, and a photo transistor on the other side. If the visual path is not blocked, phototransistor would conduct, but when something blocked the light falling on the photo transistor it wouldn’t conduct. So an encoder disc (with a proper encoder resolution) can be placed in the slot of the optical sensor to count rotation rate of a connected wheel/motor.
