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 types of speed sensors magnetic induction sensors and Infrared sensors. This 4 Pin Infrared Speed Sensor Module is used in the speed control applications where you need to read rotation of a disk. It is powered by any of the 3.3V or 5V supply and gives digital output, which you can easily read with the help of interrupt function on your microcontroller or development board.
IR Speed Sensor Module Specifications
- Groove width is about 5mm
- LM393 Comparator onboard to give digital output
- Low power requirement
- Senor output High when object is detected inn groove otherwise Low
- 4 Pins VCC, GND, Dout and Aout
To power this sensor connect either 3.3V or 5v supply to the VCC pin and connect GND pin to ground. Take the Digital Output from the DO pin and connect it to any GPIO pin on your development board or microcontroller. Read the output by AttachInterrupt function in Arduino and proceed with your program.
