4. Ecosystem Monitoring Testbed

  • Testbed for monitoring ecosystem in Lakes and Reservoirs
    • Install sensors such as water temperature, DO, turbidity
    • Real time observed data management
  • Sensors
    • Water temperature, Electrical Conductivity, Dissolved Oxygen, pH, Turbidity
  • Sensor management
    • Clean and measurement adjustment per every week
  • Real time sensor data transmission for monitoring three sites
    • Storing the real time data to database
    • Transmission efficiency comparison between RF model type andCDMA modem
  • Regular data download for monitoring other sites
