Motor Measuring Comparator Speed Sensor Module Slot Type IR Optocoupler for Arduino

The Motor Measuring Comparator Speed Sensor Module with a Slot Type IR Optocoupler is a versatile component used in various Arduino projects for detecting the speed or position of a rotating object. Below is a detailed description of the module:

Features

1. IR Optocoupler: The module employs an infrared (IR) optocoupler which consists of an IR LED and a phototransistor. The IR LED emits light, and the phototransistor detects the light.
2. Slot Type Design: The slot design allows for the detection of objects passing through the slot, making it ideal for counting rotations or detecting interruptions in the light beam.
3. Comparator: The module includes a comparator that converts the analog signal from the phototransistor into a digital signal, ensuring reliable and accurate detection.
4. Output Signal: It provides a digital output signal (high or low) that can be easily read by Arduino or other microcontrollers.
5. Adjustable Sensitivity: Some modules come with a potentiometer to adjust the sensitivity of the sensor for more precise detection.
6. Power Supply: Typically operates on a 3.3V to 5V DC power supply, compatible with most microcontroller boards.
   

   Applications

   • Speed Measurement: Used to measure the speed of rotating objects such as wheels, fans, or motors.
   • Position Detection: Useful for detecting the position of objects passing through the slot.
   • Encoder Applications: Can be part of an encoder system to provide feedback on position and speed in robotics and automation projects.
     

     Pin Configuration

     1. VCC: Connect to the positive supply voltage (usually 3.3V or 5V).
     2. GND: Connect to ground.
     3. DO: Digital output signal pin. This pin goes high or low depending on the presence of an object in the slot.The Motor Measuring Comparator Speed Sensor Module with Slot Type IR Optocoupler is a valuable tool for various Arduino projects involving speed and position detection. Its simple interfacing and reliable performance make it a popular choice for hobbyists and professionals alikePACKAGE INCLUDE :
