摘要：

With the popularization of self-service water dispensers on campuses, the way to identify users has become extremely important. In order to improve the identification method, fingerprint recognition is adopted in this design, which transmits data through ESP8266 module with STM32F103ZET6 as the processing core, stores information in the MySQL database of the upper computer, and uses Hall sensor YF-S201to collect water flow to help calculate the charges. WiFi transmission, water bill calculation, fingerprint recognition, RF card identification, and other functions of water dispensers are realized. This design not only facilitates the administrator's management of users, but also ensures the security of user information.
