Design and Implementation of an Intelligent Multi-Parameter Online Water Quality Monitoring System

A smart multi parameter online water quality monitoring system has been developed to meet the needs of intelligent water quality monitoring and multi parameter synchronous collection, combined with the impact of geological characteristics on water quality. The control module of the system is based on MSP430 microcontroller, which receives touch commands from the human-computer interaction interface through RS485 bus, and uses 4G module to obtain cloud control commands. The module sends trigger commands to the water quality sensor to read and calibrate the raw data of multiple water quality sensors in real time.To improve data accuracy, effective data processing algorithms have been adopted. The processed data is sent to the human-machine interface and cloud server through the RS485 bus using Modbus RTU protocol, thereby achieving real-time display and storage of water quality data.This device is suitable for detection needs under various geological conditions and has the ability to conduct long-term multi parameter water quality monitoring and treatment.The test results show that this multi-sensor fusion water quality monitoring system can significantly improve the intelligence and real-time performance of water quality monitoring while improving the level of ecological monitoring of water environment.
