1814-PA1 - SLOT TYPE IR OPTOCOUPLER SPEED SENSOR MODULE LM393 3.3V-5V

This speed sensor has an optical sensor that allows you to measure revolution per minute (RPM). It requires an encoder disc to count the number of times the sensor goes low to high or vice versa we can calculate the revolution in a given period of time. It has an analog and digital output. It is commonly used in robotics speed sensing printers and motor drivers.
