Design of Anti-freezing Control System for Express Cabinet Based On Mobile Application

In view of the problem that the temperature in northern China is too low in winter, and the outdoor express cabinet can't be opened due to freezing, while the temperature in summer is too high, and online shopping fresh products are prone to rot in the express cabinet, an anti-freezing temperature control system for express cabinet based on App is designed. The system adopts modular and hierarchical design, and uses App(mobile application) to connect ESP8266 module to realize remote control of STM32 single chip microcomputer and remote temperature adjustment. The system uses DS18B20 for temperature detection, and uses STM32F103C8T6 as the main controller to complete key scanning, LCD display, WiFi connection, temperature control and other functions. The system has simple circuit, convenient application, low power consumption and high precision, and has a certain market application prospect.
