IR Speed Sensor Module Based on LM393

Speed-sensing is very important in industrial applications in which process control require precise speed control of production belts to control the rate of manufacturing and also in robotics and autonomous system to determine the exact position of the arm or the tool and its movement. In industry, we use two-speed sensors: magnetic induction and infrared. This 4 Pin Infrared Speed Sensor Module is used in speed control applications where you need to read the rotation of a disk. It is powered by any of the 3.3V or 5V supplies and gives digital output, which you can easily read with the help of the interrupt function on your microcontroller or development board.
