Research And Development Of Automatic Drip Irrigation System Based On STM32

The serious shortage of water resources has become a global problem.Saving and efficient water consumption are the common needs of human production and development.China is one of the 13 countries with a serious shortage of water resources in the world.The lack of water resources has seriously hampered the sustainable economic and social development in our country and further developed into a major "bottleneck" that restricts the development of China's agricultural economy.In order to meet the people's increasing needs in the agricultural economy and improve the basic situation of agricultural water abuse,it is necessary to develop automatic drip irrigation technology to rationally allocate agricultural resources.This paper analyzes the problems of drip irrigation in agricultural water saving technology,inaccurate water resources,high labor costs and so on,and designs a set of automatic drip irrigation system based on STM32.Compared with traditional irrigation technology,it has the advantages of stable performance,wireless data transmission,precise measurement and real-time observation of data changes on the computer side,and remote control of drip irrigation system.In this paper,firstly,the measured multiple sensor parameters are fused by analyzing a plurality of factors that affect soil moisture and measuring them with a sensor.Secondly,the design of soil environment sensor detection module,data transmission module design and multi-sensor parameter fusion algorithm design of automatic drip irrigation system are completed.Thirdly,the remote monitoring module is designed and completed.The remote monitoring module can not only monitor the sensor quantity collected by the soil environment sensor module,display the consolidated soil moisture value in real time,but also remotely control the automatic drip irrigation system.Finally,a series of experiments to verify the sensitivity of the sensor to prove that the automatic control system has the advantages of high stability,accurate measurement,water-saving performance and so on.In summary,this article designed and implemented a set of automatic drip irrigation system based on STM32,with a stable working condition,good measurement accuracy,excellent water-saving performance and other advantages.It can not only accurately measure the soil temperature,soil moisture and light intensity existing in the soil,but also can realize remote control and save labor cost.It not only provides an important basis for precise planting and irrigation of agriculture,but also plays an important role in promoting the development of agriculture and forestry and promoting the growth of plants.
