Design of Temperature Remote Monitoring System Based on STM32

This paper introduces the design and implementation of a remote temperature data monitoring system based on STM32. The system uses PT100 and STM32F103VET6 main control boards to collect the measured ambient temperature. Zigbee will pass the tested data through the RS232 interface, and deliver the data to the gateway based on the MODBUS communication protocol. The gateway will upload the data to the server through the MQTT communication protocol, and the server will receive the data for caching, storage and analysis, and display it through the web page. At the same time, in order to deal with the problem of network failure, the InfluxDB standby database is deployed in the middle of the gateway.
