Soil Moisture Temperature EC Salinity 4 in 1 Sensor

Short Description:

The sensor has stable performance and high sensitivity, and can simultaneously monitor soil temperature, humidity, conductivity, salinity. It can directly and stably reflect the true moisture content of various soils and the nutrient status of the soil in time, providing a data basis for scientific planting. And we can also integrate all kinds of wireless module including the GPRS/4G/WIFI/LORA/LORAWAN and the matched server and software which you can see the real time data in the PC end.

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.

Six-tier installation

Three-tier installation

Measure Notes

3.1. The sensor needs to be used in 20% -25% soil humidity environment

2. All probe must be inserted into the soil during measurement.

3. Avoid excessive temperature caused by direct sunlight on the sensor. Pay attention to lightning protection in the field.

4. Do not pull the sensor lead wire with force, do not hit or violently hit the sensor.

5. The protection grade of the sensor is IP68, which can soak the entire sensor in water.

6. Due to the presence of radio frequency electromagnetic radiation in the air, it should not be energized in the air for a long
time.
