The Design of Data Acquisition and Management Based on the STM32 and WiFi

A data acquisition and management design is presented in the paper, which is mainly composed of microcomputer, PC, WiFi router, WiFi module and MySQL database. The WiFi module with microcomputer is set to TCP server in the Station (STA) mode, while the PC is set to TCP client, and the GUI program of windows TCP/IP data transmission is written by Qt language. After STM32 microcomputer collecting the temperature and humility data from the sensor DHT11, the data are sent to PC by means of WiFi module ESP8266, and then PC stores the data in the cloud MySQL database via Ethernet.
