Songhe F24 Capacitive Soil Moisture Sensor Module User Manual

1. መግቢያ

The Songhe F24 Capacitive Soil Moisture Sensor Module is designed for detecting soil moisture levels. Unlike resistive sensors, this module uses capacitive sensing, which contributes to its corrosion resistance and extended service life. It is suitable for various applications, including intelligent agriculture, garden watering systems, and DIY projects with microcontrollers like Arduino. The module operates within a voltage range of 3.3V to 5.5V and provides an analog output.

3.2 የወልና ግንኙነቶች

The sensor module features a 3-pin interface for connection to a microcontroller. The pins are typically labeled as follows:

• VCC (Red Wire): Connect to the 3.3V or 5V power supply of your microcontroller. Ensure the voltage is within the sensor's operating range (3.3V - 5.5V).
• GND (Black Wire): Connect to the ground (GND) pin of your microcontroller.
• Analog Out (Yellow Wire): Connect to an analog input pin on your microcontroller (e.g., A0 on Arduino). This pin provides the moisture level reading as an analog voltage.

Once connected, the sensor is ready to provide soil moisture data.

4.1 ዳሳሽ አቀማመጥ

Carefully insert the sensor blade into the soil at the desired depth. Ensure that the electronic components (the top part with the connector) remain above the soil surface to prevent damage from moisture.

4.2 Reading Data

The sensor outputs an analog voltage between 0V and 3.0V (when powered by 5V, the actual output range might vary slightly depending on the input voltage and internal regulator). This voltage is inversely proportional to the soil moisture level: a higher voltage typically indicates drier soil, and a lower voltage indicates wetter soil.

To read the data, use your microcontroller's analog-to-digital converter (ADC). For example, with Arduino, you would use the analogRead() function on the connected analog pin.

4.3 ልኬት

For accurate readings, it is recommended to calibrate the sensor for your specific soil type. This involves:

1. Dry Reading: Take a reading when the sensor is completely dry (e.g., in air or very dry soil). This will give you the maximum analog value for dry conditions.
2. Wet Reading: Take a reading when the sensor is in fully saturated soil (e.g., in a cup of water or very wet soil). This will give you the minimum analog value for wet conditions.
3. ካርታ ስራ፡ Use these two values to map the sensor's analog output to a percentage or a more intuitive moisture scale in your microcontroller's code.

5. ጥገና

Proper maintenance ensures the longevity and accuracy of your sensor.

• ማጽዳት፡ Periodically remove the sensor from the soil and gently wipe the blade clean of any accumulated soil or debris. Avoid using abrasive materials that could scratch the sensor surface.
• ዝገት፡ While designed to be corrosion-resistant, prolonged exposure to harsh chemicals or extreme conditions can still affect the sensor. Inspect the sensor blade and connections regularly for any signs of wear or corrosion.
• ማከማቻ፡ When not in use, store the sensor in a dry, clean environment away from direct sunlight and extreme temperatures.

6. መላ መፈለግ

If you encounter issues with your sensor, consider the following troubleshooting steps:

• No Reading or Constant Reading:
  • Verify all wiring connections (VCC, GND, Analog Out) are secure and correct.
  • Ensure the sensor is receiving the correct operating voltage (3.3V - 5.5V).
  • Check the microcontroller's code to ensure the analog input pin is correctly configured and read.
  • Test the sensor in both very dry and very wet conditions to see if the output changes. If it remains constant, the sensor might be faulty.
• ትክክል ያልሆኑ ንባቦች;
  • Perform a calibration as described in Section 4.3 for your specific soil type.
  • Ensure the sensor blade is fully inserted into the soil and not just touching the surface.
  • Check for any physical damage or excessive dirt/debris on the sensor blade that might interfere with readings.
  • Environmental factors like temperature fluctuations can slightly affect readings; consider environmental compensation if high precision is required.
• ዳሳሽ አልተገኘም፦
  • Confirm the power supply to the sensor is active.
  • Inspect the sensor module for any visible damage to components or solder joints.
