The Speed Detecting Sensor Groove Coupler Module is a device used to measure the rotational speed of a shaft or axle. It is typically used in combination with an Arduino microcontroller to provide an accurate measurement of speed. The module consists of a sensor, typically a photo-interrupter or a Hall Effect sensor, that is mounted in a coupler, which fits over the shaft or axle to be measured. As the shaft rotates, the sensor detects changes in the light or magnetic field and generates a signal that can be used to calculate the speed of the shaft. This information can then be used in a variety of applications, such as motor control, robotics, or data logging. The Groove Coupler Module is an easy-to-use and affordable solution for measuring rotational speed, making it a popular choice for hobbyists and educational projects. Product Images are shown for illustrative purposes only and may differ from the actual product.

Feature of Smart Speed Detecting Sensor:

• Using imported groove optical coupling sensor, width 5mm.
• It has the output state light, if the output is high level, the lights are off. if the output is low level, it is on.
• If it is covered, it will output a high level; otherwise, it output a low level.
• Good signal and waveform, with a strong driving ability for more than 15mA.
• Equipped with a fixed bolt hole, easy to install.
• Use the LM393 wide voltage comparer.
• The DO output interface can be directly connected to a micro-controller IO port if there is a block detection sensor, such as the speed of the motor encoder detection.
• DO modules can be connected to the relay, limit switch, and other functions, it can also with the active buzzer module, compose an alarm.

Applications of Smart Speed Detecting Sensor:

• Motor control: Can be used to monitor and control the speed of motors in applications such as robots, automation systems, or hobby projects.
• Data logging: Can be used to measure and record rotational speed data for analysis and monitoring.
