Design Of Potted Automatic Irrigation Control System Based On Single Chip Microcomputer

In recent years,with the rapid development of agricultural irrigation technology,the development trend of modern agricultural irrigation technique has been developed by human process and field irrigation water diversion canal irrigation process of traditional irrigation and transferred to the automatic control system of the scientific management of crop precision control.Water saving irrigation has become one of the key issues in the process of agricultural development in China.The rational utilization of water resources is an important prerequisite for the sustainable and healthy development of agriculture in china.Based on the pot research on control technology of automatic irrigation,discusses the hardware and software design of the system,system uses STC12C5A60S2 MCU as the main controller,the soil moisture detection sensor for soil moisture detection device,LCD 1602 display,electromagnetic valve actuator for irrigation,the programming of the system using the C language,puts forward the scheme of using:the soil moisture sensor,the collected pot root crops around the soil humidity data sent to the microcontroller,the data is analyzed and compared with the soil field capacity and wilting coefficient by the decision algorithm will be detected,whether to make potted crops automatic start stop irrigation,and the pot soil moisture remained within the optimum soil humidity range.Preliminary tests show that the system runs stably and has perfect functions.It can completely realize unmanned automatic control management,and has wide application and popularization foreground in rare flowers,rare medicinal herbs and potted cultivation fields.
