Product Usage

Soil Surface measure method 
1. Select a representative soil environment to clean up surface debris and vegetation
2. Insert the sensor vertically and completely into the soil
3. If there is a hard object, the measurement location should be replaced and re-measured
4. For accurate data, it is recommended to measure multiple times and take the average

Buried measure method
1. Make a soil profile in the vertical direction, slightly deeper than the installation depth of the bottommost sensor, between 20cm and 50cm in diameter.
2. Insert the sensor horizontally into the soil profile
3. After the installation is completed, the excavated soil is backfilled in order, layered and compacted, and horizontal installation is guaranteed.
4. If you have the conditions, you can put the removed soil in a bag and number it to keep the soil moisture unchanged, and backfill it in reverse order.

Three-tier installation
Six-tier installation

Measure Notes
1. All probe must be inserted into the soil during measurement.
2. Avoid excessive temperature caused by direct sunlight on the sensor. Pay attention to lightning protection in the field
3. Do not pull the sensor lead wire with force, do not hit or violently hit the sensor.
4. The protection grade of the sensor is IP68, which can soak the entire sensor in water.
5. Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long
