Optical (Infrared) Motor Encoder MMA8452Q These stickers can be readIntroduction: 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
