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
