รายละเอียดสินค้า
use:
Widely used in motor speed detection, pulse counting, position limit, etc.
Module Features:
1. Use imported slot type photocoupler, slot width is 5mm.
2. There is an output status indicator, the high-level output light is off, and the low-level output light is on.
3. If there is occlusion, the output is high; if there is no occlusion, the output is low.
4. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
5.Working voltage 3.3V-5V
6. Output form: digital switching output (0 and 1)
7, with fixing bolt holes for easy installation
8. Small board PCB size: 3.2cm x 1.4cm
9.Using a wide voltage LM393 comparator
Module use instructions:
1. When there is no cover in the module slot, the receiving tube is turned on, the DO output of the module is low, and when it is blocked, the DO output is high;
2. The DO output interface can be directly connected to the IO port of the microcontroller to detect whether the sensor is blocked, such as electricity
The code wheel can detect the speed of the motor.
3. The module DO can be connected with a relay to form a limit switch and other functions. It can also be connected to an active buzzer module.
Connected to form an alarm.
Product wiring instructions:
1.VCC is connected to the positive pole of the power 3.3-5V
2.GND is connected to the negative pole of the power supply
3.DO TTL switch signal output
4.AO This module does not work
