LM393 Motor speed measuring groove coupler sensor module

This module is widely used in motor speed detection, pulse count, etc. The working voltage of this module is 3.3V to 5V. It has fixed position holes for easy installation. With this module, you can easily calculate the speed of rotation of the wheels of your robot. . It can also be used as an optical switch. This module does not have Analog output. The DO output interface can be directly connected to a microcontroller IO port if there is a block detection sensor, such as the speed of the motor encoder can detect.

Features

1. Using imported groove optical coupling sensor, width 5mm.
2. It has the output state light, if the output is high level, the lights are off. if output is low level, it is on.
3. If it is covered, it will output a high level; otherwise, its output low level.
4. Good signal and waveform, with a strong driving ability for more than 15mA.
5. Equipped with a fixed bolt hole, easy install.
