Digital module with an optical sensor, with a gap of 6 mm. The module has a built-in comparator, because of this, the output is a digital signal. Supply voltage is from 3.3 V to 5 V. Together with the disc of the encoder, it can be used as a device counting the pulses, etc.

The sensor has a digital output that is to be attached to the pin of the microcontroller, e.g.Arduino. After power-up, at the outputs will be logical statuses 0 or 1.

Features: 

Infrared detection, eliminating the interference of external stray light

 Schmitt trigger for stable waveform and signal

 Signal output indicator ( while breaking the beam, outputs low level, the indicator lights up )

Package Includes:

1 x Photo Interrupter Sensor

1 x 20-slots encoder disk

1 x XH2.54 3PIN wire
