Design of water quality monitoring system based on NB-IoT technolog

In order to solve the problems of complexity and low efficiency of traditional water quality monitoring methods, this paper designs a water quality monitoring system combining STM32F103 microcontroller and Huawei Cloud IoT platform based on narrowband Internet of Things technology. This system can continuously collect the temperature, pH, TDS and ORP data of the automatically monitored waters of the target. The data can be automatically uploaded to the cloud platform in real time, and users can query real-time monitoring information on the HUAWEI CLOUD IoT platform, which overcomes the shortcomings of traditional water quality monitoring systems such as long data collection cycles and poor real-time performance, and has certain innovation and application value.
