"基于单片机的模拟智能灌溉控制系统研究与设计"

With the continuous development of agricultural production and the increasing scarcity of global water resources, countries around the world are actively exploring effective ways and measures to save water. The smart irrigation control system is developed to address the shortage of water resources and improve irrigation efficiency. This bachelor's thesis focuses on the study of a single-chip microcontroller-based smart irrigation control system, which monitors the temperature and humidity of the soil in real-time, sets the suitable humidity threshold based on the actual temperature value, and irrigates accordingly. The intelligent irrigation control system is based on the STC89C52 single-chip microcontroller and consists of temperature and humidity sensor DHT11 module, keypad input module, display module, water pump module, etc. The software is programmed in C language. The system functions by automatically starting the irrigation process when the soil humidity detected by the soil humidity sensor is lower than the minimum humidity value set in the system. Through testing on the hardware prototype, the system successfully achieves its intended functionality..keywords: single-chip microcomputer; sensor; LED display; water pump; irrigation.
