History has shown that over the past few decades the demand for remotely controlled systems has become increasingly popular in both commercial and residential applications. Having remote access to devices gives operators flexibly, and installs confidence about what they are monitoring is functioning correctly without having to be present. With the introduction to fly-in-fly-out (FIFO) working routines and various other careers that required similar periods of working away, remote monitoring and control can help users feel that little bit closer to home.

This project involves developing a remotely controlled, monitoring and control system for an indoor aquaponics system. Having a system such as this enables users to have the ability to maintain and monitor an aquaponics system for a period of time without the need for human interaction.

The purpose of this thesis is to document, and present information pertaining to the design, configuration, implementation, testing and final result for the monitoring and control system designed for this project. By achieving this objective, the user has the ability to remotely control and monitor an aquaponics system via a web browser interface. Included within this design is an alarming system, automated controllers, numerous sensory interfaces and data logging functionality.

Extensive research was conducted to determine firstly, the most critical elements that needs to be monitored and controlled within an aquaponics system, and Secondly, how to achieve this in the most cost effective manner.

Some of the key elements that have been examined and are included within this report are:

suitable software and development platforms
various sensors and displays available
contingency alarms, and
the development of suitable graphical displays.

A Raspberry Pi performs the function of a central host and master controller. The Raspberry Pi performs a vast array of tasks in relation to this project and is configured as a LAMP server.

An Arduino Nano has been programmed as a slave device. The role of the Arduino Nano is to: actuate the Raspberry Pi’s requests, provide the sensory information, and to monitor some of the electrical hardware.

Although this thesis is primarily focused on developing a remotely controlled monitoring and control system for an aquaponics assembly, the technology and concepts could very easily be applied to suit a wide variety of applications.
