"基于单片机的智能灌溉控制系统设计与研究"

With the continuous development of agricultural production levels and the increasingly tense global water resources, countries around the world are actively exploring effective ways and measures to save water. The intelligent irrigation control system is developed to address the shortage of water resources and improve irrigation efficiency. The single-chip microcontroller intelligent irrigation control system studied in this paper monitors the temperature and humidity of the soil in real-time, sets the appropriate humidity lower limit value according to the actual temperature value, and irrigates according to the set humidity value. The intelligent irrigation control system is based on the STC89C52 single-chip microcontroller, mainly composed of temperature and humidity sensor DHT11 module, keypad input module, display module, pump module, etc.; software is programmed in C language. The system functions are: based on the soil humidity detected by the soil humidity sensor, if the detected soil humidity value is lower than the minimum humidity value set by the system, the system automatically starts and irrigates. Through testing the hardware prototype, the system can successfully achieve the target function. This intelligent irrigation control system based on the single-chip microcontroller provides an effective solution for water-saving in agriculture and demonstrates the application and potential of smart technology in irrigation control systems.
