Design and Implementation of Intelligent Irrigation System Based on STM32 Microcontroller

With the rapid development of computer science and the rise of artificial intelligence, people’s daily lives and work methods have undergone significant changes, and intelligent technology has emerged in various industries. Currently, the air quality in some areas is polluted, and plants are an important guarantee for purifying the air. Therefore, people are increasingly paying attention to plant growth and irrigation. The main purpose of this article is to study how to achieve intelligent irrigation, which can lead to plant withering due to insufficient energy or inadequate care, while also freeing human hands and designing an autonomous irrigation system. This system is mainly based on the STM32 microcontroller for research and design. It can monitor the surrounding temperature and humidity through temperature and humidity sensors, and provide data feedback to the system. When the detected value is lower than the threshold set by the system, it will automatically start the garden automatic irrigation system, turn on the water pump to irrigate the plants, and achieve the goal of self irrigation.
