In response to today's high quality demand for agricultural products, this article designs a adoption agriculture system that combines microcontroller, Internet of Things technology, and artificial intelligence technology. This system is mainly controlled by an STM32 microcontroller and processes and judges data transmitted by sensors that detect fire, light intensity, temperature and humidity, ultraviolet intensity, and carbon dioxide concentration; And combined with IoT cloud platform technology, data can be uploaded to the cloud through the MQTT protocol to achieve remote monitoring on both mobile and PC ends; And artificial intelligence technology is used to identify crop diseases and pests. It greatly reduces human consumption, realizes the detection of intelligent agriculture, crop protection, resource optimization, and remote monitoring, and provides a feasible solution for Internet+modern agriculture.
