Buoy water quality monitoring system - AMT-FB301

The buoy water quality monitoring system (buoy-type online water quality monitoring station) is an in-situ floating, unattended water environment monitoring device, commonly known as a water quality sentinel on water. It is deployed on the water surface, anchored in place, and continuously collects water quality parameters 24/7, transmitting data wirelessly to a cloud platform for real-time monitoring and exceedance warnings.
I. System composition AMT-FB301
1. Buoy body + mooring counterweight: buoy body mostly made of polyethylene, corrosion-resistant and wave-resistant; bottom equipped with sensor bracket and counterweight; anchor rope + sinker block to fix position and prevent drifting.
2. Water quality sensors (underwater probes): standard five parameters: water temperature, pH, dissolved oxygen DO, turbidity, conductivity; extended: ORP, ammonia nitrogen, UVCOD, chlorophyll, blue-green algae, total phosphorus, total nitrogen; optional underwater camera. Sensors often come with automatic cleaning brushes to reduce biofouling and lower maintenance frequency.
3. Acquisition control unit (collector): system brain, receives sensor signals, filters, stores locally, sets acquisition intervals, supports breakpoint resume.
4. Power supply module: solar panel + lithium battery as main power, no external mains power; low-power buoy design, suitable for long-term field work.
5. Communication module: 4G/5G/NB-IoT for coastal areas; satellite communication for open sea; data uploaded to cloud platform.
6. Cloud monitoring platform: WEB/mobile APP, view real-time data, historical curves, reports; custom thresholds, SMS/platform pop-up alerts for exceedances; supports GPS positioning of buoy location.
II. Working principle
Sensors immersed in water convert physical/chemical water quality signals into electrical signals; collector processes signals; communication module uploads data to cloud platform; platform automatically stores, analyzes, and alerts.
Electrochemical electrodes: pH, dissolved oxygen; optical principles: turbidity, chlorophyll, blue-green algae; UV method: COD.
III. Application Scenarios
Drinking water source reservoirs, lakes
Urban rivers, black and odorous water treatment
Aquaculture (early warning for hypoxia, algal blooms)
National/provincial surface water monitoring sections
Offshore harbors, estuary marine monitoring
Sewage outlets, landscape lake water quality monitoring
IV. Core Advantages
✅ In-situ real-time continuous monitoring: compensates for the low frequency of manual sampling and the inability to capture sudden pollution events ✅ Simple deployment: no civil works or cable laying required; just deploy and anchor, with flexible adjustment of monitoring points ✅ Unattended operation: solar-powered, with remote viewing and remote parameter configuration ✅ Rapid pollution warning: automatic alerts when indicators exceed standards, enabling timely response to sudden pollution and algal blooms ✅ High cost-effectiveness: lower construction costs compared to fixed water quality stations
