soil moisture sensor explanation

soil sensor moisture probe RS-WS-*-TR

soil moisture sensor(RS-WS-*-TR) is a high-precision, high-sensitivity sensor for measuring soil moisture. By measuring the dielectric constant of the soil, the volume percentage of soil moisture can be measured, and the soil moisture measurement method conforming to the current international standard can directly and stably reflect the true moisture content of various soils.

Soil temperature moisture and EC sensor Instructions

Since the electrode directly measures the conductivity of the soluble salt ions in the soil, the soil volumetric water content needs to be higher than about 20%, and the soluble ions in the soil can correctly reflect the conductivity of the soil. In the long-term observation, the measured values after irrigation or rainfall are closer to the true level. If the quick test is performed, the soil to be tested can be watered first, and the water is fully infiltrated and measured.

If it is measured on a hard surface, it should be drilled first (the aperture should be smaller than the diameter of the probe), then inserted into the soil and compacted and then measured; the sensor should prevent severe vibration and shock, and can not be struck with hard objects. Since the sensor is packaged in black, the sensor will cause a sharp rise in temperature (up to 50 °C) under strong sunlight. To prevent the excessive temperature from affecting the temperature measurement of the sensor, please pay attention to shading and protection when using it in the field or in the field.

1. The three parameters of soil moisture content, conductivity, and temperature are combined.

2. Soil sensors can also be used for the integration of water and fertilizer solutions, as well as the conductivity of other nutrient solutions and substrates.

3. The electrode is made of specially treated alloy material, which can withstand a strong external impact and is not easy to damage.

4. Completely sealed, resistant to acid and alkali corrosion, can be buried in the soil or directly into the water for long-term dynamic detection.

5.High precision, fast response, good interchangeability, probe plug-in design to ensure accurate measurement and reliable performance.

6.Compact size, easy to carry, easy to install, operate and maintain

7. Good sealing can be buried in the soil of different depth for a long time

8.High accuracy and reliable performance

9.Fast response and high data transmission efficiency

10.We have three types of soil sensors,it is soil moisture sensor, soil moisture and temperature sensor, soil temperature humidity and ec sensor.
