Let's get to understand the problem space and the design requirements for our solution.
Problem Framing
Inappropriate pH and temperature causes fishes to die which leads to low production and income rate in fish farming.
Information Gathering
The fish farming production is dependent on the different parameters which include but limited to temperature, oxygen level, water pH and ammonia concentration.
In details:
• The water pH should be between 7.5 to 8.5
• Ammonia concentration should be below 0.2mg/L.
• The temperature should be within a range of 27 to 34 degrees Celsius
• Oxygen level should be in a range of 2 to 10 mg/L
Regarding an existing solution, fish farmers in Ghana already have a means of determining if the temperature has increased and the traditional method of regulating temperature and pH. However, they do not have an instrument that could measure pH in the water pond.
The team is focusing on the scope of figuring out current temperature and pH in the water pond, and possible strike back to the changes. The aim is to develop a simple and low-cost sensor package system to measure temperature and pH in fish farms and wirelessly communicate the information to users via a friendly interface. This package will be used outdoor to gather all data into a database, and data will be automatically analyzed and dispatched to the extension officers who will decide the measure fish farmers should take in case of unusual situations. The primary users of focus are Ashaiman fish farmers.
Furthermore, the team has been able to meet them in person, and their needs are summarized in the design requirement table and parameter regulations given above.
