In order to realize the accurate monitoring of the soil moisture data of dry direct seeding rice cultivation field in the cold region, a multi-level soil monitoring system for monitoring soil temperature, humidity, precipitation and other data was designed by using system integration and mobile Internet technology. The system can obtain real-time agro-meteorological information and soil status information of different depth levels, and automatically save relevant data according to the set time. Users can view the relevant information intuitively in the form of table. After further analysis, the system can meet the needs of data for dry direct seedling rice irrigation.
