Module features:
1. Adopt imported grooved optocoupler sensor with groove width of 5mm.
2, there is output status indicator light, output high level light off, output low level light on.
3, with shielding, output high level; No blocking, low output.
4, comparator output, clean signal, good waveform, strong driving capacity, more than 15mA.
5. Operating voltage 3.3v-5v
6. Output form: digital switch output (0 and 1)
7. Fixed bolt holes are provided for easy installation
8. Small board PCB size: 3.2cm x 1.4cm
9. Use wide voltage LM393 comparator
Module instruction:
1. When there is no shielding in the module slot, the receiving pipe conducts on, module DO outputs low level, and module DO outputs high level;
2. The DO output interface can be directly connected to the IO port of the single-chip microcomputer to detect whether the sensor is shielded, such as electricityMachine code plate can detect the speed of the motor.
3. The module DO can be connected to the relay to form the limit switch and other functions, and can also be connected to the active buzzer moduleConnected to form an alarm.
Product wiring instructions
:1. Connect VCC to the positive pole of the power supply 3.3-5v
2. GND is connected to the negative electrode of the power supply
3. DO TTL switch signal outputThe AO module does not work
