According to the "Guidance on Vigorously Developing Smart Agriculture" issued by the Ministry of Agriculture and Rural Affairs (Document No. 3 of 2024), "Smart agriculture is an important focus for the development of modern agriculture and a strategic high ground for building a strong agricultural nation."

With the rapid development of society and the rapid expansion of urban areas, the availability of flat land has decreased, leading to a reduction in arable land. In response, the national government has significantly increased its support for agriculture.

In modern industry and home automation, temperature sensors are increasingly used, and serial input and output (Serial IO), as its main communication method, has shown many advantages, making it frequently used in temperature sensors.

In the past decade, some developed countries and regions in the United States and Europe have successively carried out demonstration research on the application of Internet of Things in the "agricultural field", realizing the practice and promotion of Internet of Things in agricultural production, resource utilization, agricultural product circulation, and precision agriculture. At the same time, it has also promoted the interconnection of agricultural Internet of Things with other Internet of Things, laying the foundation for the establishment of ubiquitous Internet of Things.

IoT technology is developing rapidly, and the field of IoT smart agriculture is undergoing major changes with the development of wireless technology. In this revolution, LoRa modules are playing an increasingly important role in agricultural data collection and control with their unique advantages. This article will conduct an in-depth discussion of the application of LoRa modules in the agricultural field, and analyze its technological innovation and practical application effects.
