System Overview

How ChitoNet Works

A distributed network of smart buoys working together to monitor and protect aquatic ecosystems.

1. Deploy Buoys

Smart buoys equipped with ESP32-DevKitC V4 are strategically placed across large water areas, forming a monitoring network.

2. Continuous Monitoring

Each buoy continuously measures pH levels, water temperature, turbidity, and dissolved oxygen, detecting early signs of eutrophication.

3. Early Detection

Real-time data analysis identifies potential algal blooms and nutrient imbalances before they become critical.

4. Chitosan Treatment

When threats are detected, chitosan mixture can be deployed to prevent eutrophication and maintain water quality.

Technology

Advanced Sensor Array

Four critical sensors working in harmony to provide comprehensive water quality assessment.

pH Sensor

Measures acidity and alkalinity levels in real-time. Critical for detecting chemical imbalances that can lead to eutrophication. Monitors pH range from 0-14 with high precision.

Why it matters: Algal blooms often cause pH fluctuations

Temperature Sensor

DS18B20 waterproof sensors track water temperature with ±0.5°C accuracy. Temperature changes can accelerate algal growth and indicate thermal pollution.

Why it matters: Warmer water promotes faster nutrient absorption

Turbidity Sensor

Optical sensors measure suspended particles and water clarity in NTU (Nephelometric Turbidity Units). High turbidity indicates sediment, algae, or organic matter presence.

Why it matters: Direct indicator of water quality degradation

Dissolved Oxygen Sensor

RS485 industrial-grade sensor measures oxygen levels in water. Low DO indicates eutrophication as algae consume oxygen during decomposition, creating dead zones.

Why it matters: Critical indicator of aquatic ecosystem health

Network Architecture

Distributed Buoy Network

ChitoNet operates as a distributed network of intelligent buoys, strategically positioned across large water bodies like a monitoring net. Each buoy operates independently while contributing to a comprehensive view of water quality across different areas.

ESP32-DevKitC V4

Each buoy is powered by ESP32-WROOM-32D, enabling dual-core processing, wireless data transmission, and remote monitoring capabilities.

Area Coverage

Buoys are deployed across large areas, providing spatial data about water quality variations in different zones.

Real-time Data

Continuous monitoring with instant data transmission allows for immediate response to changing conditions.

Prevention Technology

Chitosan-Based Eutrophication Prevention

When early warning signs are detected, ChitoNet enables proactive intervention using chitosan mixtures.

How Chitosan Works

Chitosan, derived from chitin, is an eco-friendly biopolymer that effectively binds with excess nutrients (particularly phosphorus) in water. When deployed as a mixture, it prevents these nutrients from being available to algae, thus stopping eutrophication before it starts.

✓ Biodegradable and environmentally safe
✓ Targets excess phosphorus and nitrogen
✓ Prevents algal bloom formation

Automated Response

When sensors detect parameters indicating potential eutrophication (e.g., rising pH, increasing turbidity, temperature spikes), the system can trigger chitosan mixture deployment in the affected area, providing immediate preventive action.
