With the rapid development of industry and agriculture, water pollution is found everywhere, and the protection of water resources has attracted increasing attention. For a long time, drinking water pollution was measured manually, which is time-consuming and laborious. To effectively detect and evaluate drinking water pollution, a drinking water quality monitoring and evaluation system is designed. The system can perform real-time measurements of water temperature, conductivity, turbidity and other parameters. The measurement results can be displayed on an LCD screen and can be transmitted remotely. The system can be used to detect the contamination of drinking water resources, such as surface water and groundwater, and to judge whether the water quality is qualified according to the set threshold parameters. The test results demonstrate that the system can realize dynamic monitoring and evaluation of drinking water resources. In addition, the system can provide effective data for water resource environmental protection.
