Soil moisture and temperature are important components of the soil and play an important role in crop growth and water-saving irrigation. Only by understanding the soil moisture can we understand the amount of water needed for irrigation. This can not only rationally use water resources, but also reduce land salinization and water loss. The soil moisture temperature recorder can be used to measure the soil moisture. Through the GPS positioning system, the distribution of moisture in the soil can be used to provide scientific basis for differential water-saving irrigation. At the same time, accurate water supply can also improve crops. The yield and quality. Jiangsu Aoli New Materials Co.,Ltd , https://www.jsaolimaterials.com
The instrument mainly measures soil moisture, but in order to meet customer requirements, our company added soil temperature measurement based on the original measurement of moisture, which can solve the soil moisture and soil temperature at the same time. Its functional characteristics are: RS-232 communication interface and computer communications, while increasing the GPS positioning function. 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. .
In the process of testing, the time spent on the test is as short as 2 seconds at most. The error value of both the absolute error and the relative error is very small, so that there is no fear of miscalculation of the final result due to the measurement error. . Water storage data up to 20,000 groups, data download and storage, storage files can be directly imported into EXCEL, so that when the summary is easy to observe and analyze.
