Soil moisture measurement instrument details

Details of soil moisture measurement instruments Introduction Soil moisture, or soil moisture, is the most important and commonly used soil information. It is the basis for scientifically controlling the regulation of soil moisture for water-saving irrigation, scientific water use, and irrigation automation. Rapid and accurate determination of soil moisture in farmland is of great significance for the determination of soil moisture during crop growth and development in order to make decisions such as irrigation, fertilization, or drainage measures. Therefore, monitoring of soil moisture content can not be separated from various agricultural water and soil engineering management, agricultural experiment, agricultural meteorology, irrigation management and drought monitoring. Soil moisture measurements can be monitored using a timed soil moisture detector.
Quick Soil Moisture Analyzer is a GPS positioning system to master the distribution of soil moisture (water content) to provide scientific basis for differential water-saving irrigation. At the same time, accurate water supply is also conducive to improving crop yield and quality. This measuring instrument was only able to measure the soil moisture at the very beginning, but later added the function of measuring the soil temperature because of the customer's needs. This test instrument has three different models, namely TZS-IW type, TZS-W type, TZS-IIW type. Here's a simple look at the differences between these three instruments:

Functional differences

The direct measurement shows the soil moisture and temperature content. It has data storage and is stored directly on the host.

The RS-232 communication interface communicates with the computer. The dedicated data download software can directly measure the soil moisture and temperature values, and can also measure the time and moisture and temperature content data of each sampling in real time, store it in the host computer, and can be connected with the computer. The data is exported and the software has a storage and printing function (software give-away) to analyze the moisture distribution in the computer.

With all the features of TZS-W, GPS positioning has been added. While measuring the soil moisture content and temperature, together with the GPS can measure the precise information (longitude, latitude) of the measuring point, the position information of the sampling point can be displayed directly, and thus, the spatial difference of soil moisture can be reflected. Not only is it beneficial to the implementation of water-saving irrigation, but the precise water supply also helps to increase the yield and quality of crops. The automatic sampling and processing of water content and three-dimensional position information are realized. The signals of sensors and GPS receivers are processed and the corresponding data are calculated. The functions of display, storage and communication are available, and the distribution of moisture can be analyzed in the computer. .
