IR infravörös réses optikai sebességmérő érzékelő Optocsatoló modul motorteszthez PIC AVR

IR infravörös réses optikai sebességmérő érzékelő Optocsatoló modul motorteszthez PIC AVR
IR Infrared Slotted Optical Speed Measuring Sensor Optocoupler Module For Motor Test PIC AVR
Use:
It is widely used in motor speed detection, pulse counting, position limit, etc.
Module features:
1. Use imported slot-type optocoupler sensor with slot width 5mm.
2. There is an output status indicator, the output high-level light is off, and the output low-level light is on.
3. With obstruction, output high level; without obstruction, output low level.
4. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
5. Working voltage 3.3V-5V
6. Output form: digital switch output (0 and 1)
7. Equipped with fixing bolt holes for easy installation
8. Small board PCB size: 3.2cm x 1.4cm
9. Use wide voltage LM393 comparator
Module instructions:
1. When there is no block in the module slot, the receiving tube is turned on and the module DO outputs low level; when blocked, 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 covered or not. If a motor encoder is used, the motor speed can be detected.
3. The module DO can be connected to a relay to form a limit switch and other functions, or it can be connected to an active buzzer module to form an alarm.
Product wiring instructions:
1. Connect VCC to the positive pole of the power supply 3.3-5V
2. GND connects to the negative pole of the power supply
3. DO TTL switch signal output
4. AO This module does not work
