Project Background

Laguna de Bay is the largest lake in the Philippines and supports fisheries, aquaculture, irrigation and surrounding communities. Like many large shallow lakes, it can be affected by nutrient input, algae growth, suspended solids and changes in dissolved oxygen.

For lake management and aquaculture-related monitoring, early warning of algae growth is important. By the time water color changes are visible, the lake may already be experiencing strong biological activity or oxygen stress.

Monitoring Challenge

Lake monitoring requires more than pH or temperature. Chlorophyll and blue-green algae data are useful for tracking algae growth trends, while dissolved oxygen and turbidity help evaluate water stability and ecological condition.

YexSensor Recommended Solution

YexSensor recommends combining chlorophyll, blue-green algae, dissolved oxygen and turbidity sensors for lake algae monitoring. The system can be installed on a floating platform, buoy station or near-shore fixed point.

This configuration provides continuous online data and helps the operator identify algae risk earlier than manual visual inspection.

Recommended Product Configuration

Product Image	Model / Product Link	Configuration Role
	YEX-S2-CHLO-8S Online Chlorophyll Sensor	Tracks chlorophyll concentration and algae growth trend
	YEX-S2-BGA-8S Online Blue-Green Algae Sensor	Supports cyanobacteria risk warning
	YEX-S1-RDO Optical Dissolved Oxygen Sensor	Monitors oxygen stress and lake ecological condition
