Design and realization of meteorological data collection and classification system based on Stm32

Abstract

Since the meteorological industry is developing well, the development of meteorological collection technology is more and more rapid. Nowadays, the manual collection technology has gradually fall and gradually replaced by automatic collection. Data collection and transmission are the main steps of meteorological collection. The system consists of software system and hardware system. The hardware circuit includes STM32 single chip, 4G chip, DHT11 temperature and humidity sensor, PM2.5 sensor, photosensitive sensor and sulfide sensor. The software design includes server design and database design. The system first collects data from the hardware circuit, and then uploads it to the server after corresponding processing. After receiving the information, the receiving end can display it through the server terminal.
