AI in FabAcademy understanding

The choice of soil moisture sensor depends on your project's budget, accuracy requirements, and durability needs. Here are some common options:

  1. Capacitive Soil Moisture Sensor (e.g., v1.2)
  2. Advantages: More durable and less prone to corrosion compared to resistive sensors.
  3. Accuracy: Provides stable readings.
  4. Recommendation: Ideal for longer-term projects or those requiring consistent performance.
  5. Connection: Works with Arduino's analog input pins.

  6. Price: Mid-range.

  7. Resistive Soil Moisture Sensor

  8. Advantages: Inexpensive and easy to find.
  9. Accuracy: Adequate for basic applications but may degrade over time due to corrosion.
  10. Recommendation: Suitable for short-term or budget projects.
  11. Connection: Analog or digital pins.

  12. Price: Low.

  13. Soil Moisture Sensor with Temperature and Humidity (e.g., DHT11 or DHT22-based)

  14. Advantages: Combines multiple measurements (soil and air humidity/temperature).
  15. Accuracy: High, but may require additional calibration.
  16. Recommendation: Useful for more complex systems or precision agriculture.
  17. Price: High.

Best Option for Your Project:

The Capacitive Soil Moisture Sensor is recommended for this mint-growing system. It offers good accuracy, is easy to use with Arduino, and does not corrode in moist environments. If you have a limited budget, a resistive sensor can work but may need periodic replacement.
