Abstract

This paper mainly introduces an intelligent agricultural system based on STM32 single chip microcomputer and PLC, aiming to realize the automation and intelligence of agricultural production. The system uses STM32 single chip microcomputer to collect environmental data, and uses PLC to control it in real time, to optimize agricultural production environment. Specifically, the system collects environmental data such as soil moisture, air temperature and humidity, and light intensity through STM32 microcontroller, and upload the data to the cloud using MQTT protocol to achieve remote monitoring. At the same time, the system uses PLC to analyze the collected data in real time, and automatically adjust the agricultural production equipment, such as pumps, ventilation fans, etc., to achieve automatic control. This system can not only reduce the labor intensity of farmers, but also improve agricultural output and product quality, and has a good application prospect.
