Online multi parameter water quality monitoring system: The system supports second level data collection, breaking through the bottleneck of manual sampling time. [Model recommendation: TH-QSZ07, IoT integrated device, cloud environment Tianhe supports customized services] The online multi parameter water quality monitoring system breaks through the bottleneck of traditional manual sampling in terms of timeliness, frequency, and data continuity through second level data collection, real-time transmission, and intelligent analysis technology, providing high-precision and high-efficiency solutions for water quality management. The sensor adopts anti-interference design (such as anti biological adhesion coating, temperature compensation algorithm), adapts to complex water environments (such as high salt, high turbidity, and highly corrosive wastewater), and ensures second level data accuracy (error ≤± 2%). Manual sampling requires on-site water collection and laboratory analysis, which takes a long time (usually ≥ 4 hours) and is difficult to capture sudden changes in water quality (such as chemical leaks and algal blooms). The online system implements second level data updates. When water quality parameters (such as COD and ammonia nitrogen) exceed the standard, the system immediately triggers warnings (SMS, APP push, platform pop ups), and management personnel can respond in a timely manner to avoid pollution diffusion.
