Продукт закінченийview і особливості
The Youmile LM393 H2010 sensor module is a slot-type optocoupler designed for precise detection. It integrates an LM393 comparator chip for stable signal output.
- Signal Output Indication: The module includes an LED indicator for visual feedback on the output status.
- Single-Channel Signal Output: Provides a single digital output signal.
- Output Logic: Outputs a high level (LED light off) when an obstruction is present in the slot, and a low level (LED light on) when there is no obstruction.
- Fixed Sensitivity: The sensitivity of the sensor is not adjustable.
- Застосування: Suitable for workpiece counting and motor speed measurement using an encoder disc.
- Circuit Board Output Switch: Refers to the digital output capability of the module.

Налаштування та підключення
Follow these steps to connect your LM393 H2010 sensor module:
- Визначення пінів: The module has three pins:
- VCC: Power supply input (DC 5V).
- GND: З'єднання заземлення.
- ВИХІД: Digital signal output.
- Підключіть живлення: Connect the VCC pin to a stable 5V DC power source and the GND pin to the ground of your system (e.g., Arduino, microcontroller).
- Вихід підключення: Connect the OUT pin to a digital input pin on your microcontroller. This pin will provide the detection signal.
- Integration with Encoder (for speed measurement): If using for motor speed measurement, mount the encoder disc onto the motor shaft. Position the sensor module so that the encoder disc passes through the sensor's slot. Ensure the disc moves freely without obstruction from the sensor housing.

Інструкція з експлуатації
Once properly connected, the sensor operates by detecting the presence or absence of an object within its 10mm slot.
- No Obstruction: When the sensor's infrared beam is unobstructed (nothing is in the slot), the output pin (OUT) will be LOW, and the onboard LED indicator will be ON.
- Obstruction Detected: When an object (e.g., an encoder disc tooth, a workpiece) passes through the slot and breaks the infrared beam, the output pin (OUT) will go HIGH, and the onboard LED indicator will turn OFF.
Your microcontroller can read these HIGH/LOW transitions on the OUT pin to count events (like workpiece passes) or calculate speed (by measuring the frequency of transitions from an encoder disc).
Додатки
- Workpiece Counting: Integrate the sensor into an assembly line to count items as they pass through the slot.
- Motor Speed Measurement: Attach an encoder disc to a motor shaft. The sensor detects the slots on the disc as it rotates, allowing for calculation of RPM.
- Position Detection: Can be used to detect the presence or absence of a component at a specific point.
Технічне обслуговування
- Keep the sensor's slot clean and free from dust or debris, which could interfere with the infrared beam.
- Періодично перевіряйте всі з'єднання проводів, щоб переконатися в їх надійності.
- Store the module in a dry, non-corrosive environment when not in use.
Усунення несправностей
| проблема | Можлива причина | Рішення |
|---|---|---|
| No output signal / LED always ON/OFF | Incorrect wiring, no power, faulty module, continuous obstruction/no obstruction. | Verify VCC and GND connections. Ensure 5V power is supplied. Check OUT pin connection to microcontroller. Test with a known obstruction/no obstruction. |
| Непослідовні показання | Loose connections, dust in slot, unstable power supply, object not fully breaking beam. | Secure all connections. Clean the sensor slot. Ensure power supply is stable. Adjust object positioning to fully interrupt the beam. |
| Motor speed measurement is inaccurate | Encoder disc not properly aligned, disc slipping, incorrect software logic. | Ensure the encoder disc is centered and securely attached to the motor shaft. Verify the sensor is positioned correctly over the disc. Review your microcontroller code for pulse counting and speed calculation. |
