Research on Wireless Water Quality Monitoring Method Based on STM32

Abstract

Since the 21st century, people’s production and life have caused water pollution to varying degrees, so real-time monitoring of water quality has become crucial. Based on STM32, this paper proposes a water quality monitoring method that can continuously monitor three water quality parameters: water temperature, PH value, and turbidity. The water quality monitoring method is mainly based on the extended circuit of the STM32 series single-chip microcomputer, including PH sensor control circuit module, temperature sensor circuit module, wireless network communication circuit module, turbidity sensor circuit module, etc. Then based on the C language to write the MCU data acquisition program and the PC program developed on the virtual instrument design language platform, the PC program is mainly composed of the main PC and the MCU communication, data analysis and processing, process monitoring and other subroutines. The water quality monitoring method proposed in this paper can detect different water quality in real time through wireless transmission. This new method is not only suitable for the future development of the current water quality monitoring market, but also has a very promising application prospect.
