Seawater Ocean Online Monitoring System —— Salinity DO pH Multi-parameter Buoy Monitoring Solution

Introduction

With the construction of marine ranches, the expansion of offshore aquaculture scale, and the continuous strengthening of marine ecological protection, real-time seawater quality monitoring has become a key means to ensure the sustainable utilization of marine resources. Traditional manual sampling methods have problems such as poor timeliness, small coverage, and data lag. Especially under harsh sea conditions, it is difficult to carry out continuous monitoring, often resulting in sudden decreases in dissolved oxygen, abnormal salinity fluctuations, pH changes and other issues not being discovered in time, causing large-scale aquaculture losses or ecological abnormalities.

Industry Pain Points

The marine environment is complex and changeable, with high salinity, high humidity, and strong corrosion placing extremely high requirements on equipment. Conventional equipment is prone to aging and failure, and data cannot be obtained remotely in real time, making it difficult to meet the urgent need for high-frequency and continuous data in refined management of marine ranches and ecological research. Once sudden events such as red tides and hypoxia occur, the best intervention opportunity is often missed, resulting in huge economic losses.

Why Online Monitoring is Needed?

Real-time, continuous, multi-parameter online monitoring systems can collect data 24 hours a day without interruption, instantly upload to the cloud platform through wireless transmission, and achieve remote early warning and scientific decision-making.

Our Solution

YEX Seawater Ocean Monitoring System adopts high salt corrosion-resistant sensors (YEX-S2-EC-S salinity sensor, YEX-S2-RDO dissolved oxygen sensor, YEX-S2-PH pH sensor, YEX-S2-ZS turbidity sensor), combined with buoy platforms, solar power supply, 4G/satellite communication and GPS positioning technology. It can operate stably in nearshore, offshore and tidal flat environments. The system supports automatic data upload to the cloud platform, providing reliable data support for marine ranches, ecological monitoring and scientific research, effectively reducing risks and improving management efficiency.

Seawater Ocean Online Monitoring System Architecture

The system adopts a layered IoT architecture:

Sensor layer (immersed in seawater) → Buoy acquisition layer (data processing and storage) → Communication layer (4G/satellite transmission) → Cloud platform layer (data analysis and visualization) → Application layer (user terminal + scientific research platform).

Working Principle: Sensors continuously collect seawater parameters, process them through the collector and upload to the cloud platform in real time via wireless network. The platform automatically performs data verification and threshold comparison, immediately pushes alarms when abnormal, and generates historical curves and analysis reports, realizing a complete closed loop from "data collection" to "intelligent decision-making".
