摘要
农田湿度是农业中考量自然环境的重要因素,为了保证农田湿度适合农作物良好生长,设计了一套基于STM32/AT89C51单片机的农田精准灌溉智能监测及控制系统。系统主要功能:结点湿度传感器检测土壤湿度并发送到单片机,结点单片机将土壤湿度传感器检测到的土壤湿度模拟量传给主机单片机转换成数字量显示到LED显示器;若需灌水,则手动控制按下主机开启按钮通过485传输控制电磁阀进行滴灌或自动控制下湿度超过设定的最低下限进行倒计时定时灌水。现研究了一套基于STM32的农田节水灌溉系统,以期达到实时掌握和控制农田湿度的效果。
Farmland humidity is an important factor in the natural environment of agricultural.In order to ensure that the field moisture is suitable for the growth of crops,aprecision irrigation system based on STM32/AT89C51 single chip microcomputer was designed.Main function：node humidity sensor to detect soil moisture and sent to the microcontroller,single chip digital display to LED display and mobile phone;irrigation if necessary：could controll it by auto-control or manual control through 485.In this study,a water-saving irrigation system based on STM32 was studied in order to achieve real-time control and control of the effect of farmland moisture.
