Water quality monitoring system for water intake: on-site rapid and real-time monitoring of water quality in the water source area to ensure water supply safety. [Model recommendation: TH-QSZ07, IoT integrated device, customized service supported by Yunjing Tianhe] The sensors of the water quality monitoring system are equipped with anti biological adhesion coatings, temperature compensation algorithms, and self-cleaning devices to adapt to complex water environments (such as high salt, high turbidity, and highly corrosive water sources), ensuring data stability (error ≤± 3%). When water quality parameters (such as COD and ammonia nitrogen) exceed the preset threshold, the device immediately triggers a local alarm (such as sound and light prompts, SMS push), and uploads warning information to the cloud platform. This system achieves real-time on-site monitoring, with a data update frequency of seconds and a warning response time reduced to minutes, striving for golden disposal time for water supply safety. The monitoring system of a water source in a certain city detected a sudden drop in residual chlorine at night, and the system sounded an alarm within 10 seconds. The water plant immediately switched to a backup water source, avoiding large-scale water supply pollution.
