Design of an Automatic Soil Moisture Regulation System Based on a Microcontroller
Abstract：To improve the automated management level of soil moisture in agriculture, an automatic soil moisture regulation system based on a microcontroller was designed. The system takes the STM32 microcontroller as the core, integrating hardware devices such as a soil moisture sensor, analog-to-digital conversion module, water pump, and solenoid valve drive module. It also combines high-precision data acquisition and processing algorithms to achieve real-time monitoring and precise adjustment of soil moisture. The system software uses a PID control algorithm to dynamically adjust irrigation time and water volume, ensuring that soil moisture remains within the set range. Test and verification results show that the system has high accuracy and stability, effectively controlling irrigation, reducing water waste, and improving agricultural production efficiency.
