Using the Optical Coupler Speed Measurement Module
In this project, I will talk about Phototransistor Optical Interrupter Switches (Opto Coupler) Module, how this module works and helps in determining the speed of a rotating object and finally I will show you how to Interface Optical Interrupter Switch Sensor. This tutorial is a comprehensive, practical guide to the Speed Sensor / Tacho Sensor (Slot-Type Optocoupler) (Leobot Product #245). Measure rotation speed (RPM) with Optocoupler and Encoder disk and Arduino - Quick and Easy! Beginner Protip 12 minutes 64,451 When building a robot car, it is important to control the speed of the rotation of the wheels. An optocoupler sensor is a gadget that uses "electricity-light-electricity" conversion to keep the input and output circuits electrically isolated.
