Optical Motor Shaft Encoder

Optical (Infrared) Motor Encoder is a speed sensor.it is a type of tachometer that is used to measure the speed of a rotating object like a motor.

It have an implemented contactless digital tachometer.

There are many types of Speed Sensor like Hall-effect based sensors, Magnetoresistive Speed Sensor, etc.

Optical (Infrared) Motor Encoder inexpensive Infrared based Speed Sensor.

Speed sensors serves the same purpose: help us determining the rotational speed of a rotating objec

Optical (Infrared) Motor Encoder Module  uses LM393 Speed sensor with Arduino.

The LM393 Speed Sensor Module is basically an Infrared Light Sensor integrated with LM393 Voltage Comparator IC.

Features:

•  Main chip: LM393
• Operating voltage: 5V
• Photointerrupter Width:10mm
• Diemensions : 25mm x 20mm x 15mm
