Definition of VCC power supply is, GND power negative, DO digital output, AO is invalid

USES:

Widely used in motor speed detection, pulse count, the position limit, etc.

The module features:

1, using imported trough type optical coupling sensor

2, groove width 5 mm.

3, the output state light, lamp output level, the output low level light.

4, covered, output high level; Without sunscreen, the output low level.

5, the comparator output signal is clean, good waveform, driving ability is strong, for more than 15 ma.

6, the working voltage of 3.3 V to 5 V

7, output form: digital switch output (0 and 1)

8, has a fixed bolt hole, convenient installation

9, small board PCB size: 3.2 cm x 1.4 cm

10, use the LM393 wide voltage comparator

Module USES:

1. The module without slot, the receiving tube conduction, module DO output low level, shade, the DO output high level;

2. DO modules can be connected to the relay, limit switch, and other functions, can also with the active buzzer module, alarm.
