5mm Slit Sensor Module, Encoder, Optocoupler, Detector with LM393 Comparator Arduino

A module with a very wide range of applications. In conjunction with the encoder disk it is possible to use, for example, when calculating the rotational speed of motors, counting pulses, etc. The slotted sensor, i.e. the slotted optocoupler, sends a signal depending on whether the aperture is covered or not. The user can choose between two output signals from the sensor:
- digital
- analog
The digital signal is a signal in the logical form 1 - i.e. voltage - 5V or logical 0 - i.e. GND of the mass, so no signal. The analog signal is a linear signal with higher resolution, so it does not distinguish only between 0 and 1, but the entire range from 0 to 5V power supply, and depending on the sensor condition it sends such a signal. So it can be a 0V signal and a small change of the sensor state causes the voltage of the output signal to increase gradually to the maximum.
