Project Background

Water bodies near livestock or agricultural activity areas are often sensitive to nitrogen and organic pollution. In the Nanchang monitoring scenario, the key task is to observe whether nearby discharge, runoff or pond water exchange causes ammonium nitrogen and COD to increase.

Because pollution impact may appear intermittently, continuous online monitoring is more effective than isolated sampling. Trend data can show when values rise, how long the change lasts, and whether turbidity or conductivity changes at the same time.

How YexSensor Solves It

The recommended configuration uses ammonium nitrogen and COD sensors as the core monitoring devices, supported by turbidity, conductivity and pH sensors. This combination helps identify organic pollution, nitrogen pollution, runoff disturbance and abnormal water source changes.

The sensors can be installed at key inlet, outlet or nearby water body positions. With RS485 Modbus RTU output, data can be connected to a local station or remote monitoring platform for long-term trend analysis.
