In order to avoid the influence of frost and hail on the growth of apple, an intelligent disaster prevention system based on STM32F417IGT6 is designed. The system adopts the method of combination of software and hardware, with STM32F417IGT6 as the main control chip, and obtains weather information through DHT11 digital temperature and humidity sensor. In addition, the system uses ESP8266 for wireless communication, and corresponding protection measures are designed for frost and hail weather. The designed system allows users to take timely countermeasures before the arrival of frost and hail to increase apple production. The field test and experimental data of the prototype show that the system can give an early warning to the users 20 minutes in advance, and fully start the protective device within 2 minutes, which has the characteristics of low cost, fast response speed and strong protective function, and has high application and promotion value.
