Thank you for choosing our soil sensor. Please read this manual carefully to understand its functions and services. The soil sensor features a probe made of austenitic 304 stainless steel, offering excellent corrosion resistance and toughness. The accompanying mobile APP allows you to view real-time moisture data and can integrate with our smart garden timer for automatic intelligent irrigation.

Product Features

• Monitor real-time soil moisture and temperature.
• View historical record curves via the mobile APP.
• Linkage with our smart garden timer for automatic irrigation.
• Powered by two AA batteries, offering low power consumption and extended battery life.
• Utilizes a highly sensitive probe for fast response, stable and reliable, accurate measurements.
• Quick plug-in design for easy measurement.

Product Parameters

Note: These are the details of all measurable parameters. Please take actual sensor data as the final standard.

Application Scenes

The soil sensor is suitable for various gardening applications, meeting soil moisture measurement needs for different plantations to provide comprehensive care for flowers and plants. Examples include farms, greenhouses, orchards, nurseries, garden lawns, potted plants, and garden horticulture.

   Visual: The Tuya app interface for adding devices is displayed.

3. Step 3: Ensure the sensor is in pairing mode (LED is blinking).

   Visual: The soil sensor is shown with a blinking LED indicator.

4. Step 4: Enter the pairing mode interface; the gateway will search for the device.

   Visual: The Tuya app is shown searching for devices.

5. Step 5: Add the sensor to the gateway and complete the connection.

   Visual: A confirmation screen shows the device has been successfully added.

6. Step 6: View the soil sensor data in the app.

   Visual: The mobile application interface displays current readings for soil humidity at 38% and temperature at 29°C.

Product Notes and Test Considerations

Product Notes:

• Install the sensor by inserting the probe vertically into the soil.
• Ensure the probe is in full contact with the soil and compacted to guarantee data accuracy.
• The soil sensor is designed for soil and mud only; it is not applicable to flour, prickly pear, organic crumbs, liquid particles, etc.
• When installing, try to insert the probe into the soil as a whole unit.
• The depth and tightness of the probe's contact with the soil directly affect data values and can lead to errors. For improved accuracy, use multi-point testing and calculate the average value.
• When measuring, avoid touching stones and do not use excessive force to push the probe, as this can easily damage it.
• After measurement, clean the probe promptly with paper or a cloth.
• When the sensor is not in use and stored, do not rub or scratch the probe directly with your hands. Keep it clean, dry, and away from magnetic objects and other metal items.
• Please follow proper waste battery recycling procedures to avoid environmental pollution.

Test Considerations:

1. Optimal Moisture Levels: Dry, sandy, or overly fertile soil may affect accuracy. If the soil is dry, splash some water around the sensor and wait for 30 minutes before testing. Moisture levels between 40%-70% are considered optimal.
2. Data Variability: Differences in soil depth, density, and humidity at various points can influence data accuracy. Perform multiple measurements at different locations and depths, ensuring consistent contact and compaction around the probe, then take the average value. Thoroughly clean the probe with paper or an abrasive cloth before each remeasurement.
