In order to improve the utilization rate of the total solar radiation and make it play a greater role, the industry realizes the monitoring of the total solar …
background： Although the existing water-saving irrigation system has obvious effects on reducing the cost of crop irrigation and improving the crop yield. However, the rationality of irrigation cannot be effectively implemented due to many problems to be solved in the conventional drip irrigation system. The main problem: the randomness of manual operation is too large, …

background： Soil moisture sensor, also known as: soil moisture sensor, soil moisture sensor, soil moisture sensor, is mainly used to measure soil volumetric water content. Soil moisture sensors commonly used in soil moisture monitoring and agricultural irrigation and forestry protection are FDR type and TDR type, namely frequency domain type and time domain type. At …
Summary: Rain and snow, both natural precipitation phenomena, are caused by disturbances in the atmospheric circulation and are an integral part of the earth’s water cycle. They are also the only way to replenish water for terrestrial organisms that live far from rivers and lakes. Precipitation is the origin of surface runoff and the main …
