Smart Farmland Monitoring and Management System Based on STM32 and Multiple Sensors

Agriculture is facing severe challenges of continuous decline in primary industry workers and loss of arable land, coupled with the reduction of natural resources, arable land, and unpredictable weather conditions, making food security a major issue. Precision agriculture, also known as intelligent agriculture, utilizes advanced information technology, sensing technology, positioning technology, and data analysis (DA) of the Internet of Things to finely manage every aspect of agricultural production, achieve intelligent control of agricultural production, and realize a new agricultural model that is efficient, high-yielding, high-quality, and environmentally friendly. This model has become an important guiding direction for agriculture in China. This article is based on STM32 and multiple sensors for real-time monitoring of Soil humidity and temperature, combined with sensors such as light intensity, atmospheric temperature/humidity, and CO2 concentration, to construct a holographic perception network for agricultural ecological environment and optimize precise management of agricultural production. This system can not only improve agricultural production efficiency and reduce resource waste, but also provide scientific decision support for farmers, promoting the development of agriculture towards intelligence and sustainability.
