Remote Aquaponics Sensor Buoy
Project Members
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
Solar Panel - Due to latitude (1.5
o south), the panel can be laid flat.
-
Mintyboost (Regulator from battery for 5V devices)
-
Due to Li-Ion sensitivity to weather conditions and its cost, look into using NiCd or Sealed Lead Acid
Control
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.

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