Remote Aquaponics Sensor Buoy

Project Members

Originated By Vishal Rana

Project Goal

  • Deploy a buoy with sensors that monitors chemical concentrations in an aquaponics system fish tank.
  • The buoy will have its own power production and storage capabilities.
  • It should provide daily updates from anywhere in the world.

Current Plan

Power

Due to Li-Ion sensitivity to weather conditions and its cost, look into using NiCd or Sealed Lead Acid

Control

  • Diavolino need 4.5V - 5.5V. It will work well with 5V regulator connected to the batter charger load terminal
  • Might have to use a Mega due to need for multiple baud rates.
  • Will need to turn phone and the arduino on and off to save energy

Communication

  • Use a Motorola C168i controlled by Arduino via serial library to send text messages. Tutorial
  • Cost of sending international texts using Safaricom is approx. 11 cents/text. Safaricom Rates

Sensors

  • Dissolved Oxygen
    • Atlas Scientific Probe - They have sample arduino code. Calibration is good for atleast 12 months after initial calibration – $200
  • Ammonia
  • Nitrate
  • pH
