Working Principle – A brief Overview

Overview of StockFeesh Block Diagram

StockFeesh compromises of 2 systems which are in charge of cleaning the fish tank water in the main fish tank

System 1 (Pink) ~ Responsible for tracking main fish tank parameters using sensors as well as activating the water change cycle when the environment is too ‘dirty’, draining the dirty water out and pumping water into the main water tank
System 2 (Blue) ~ Responsible for treating tap-water for fishes to thrive in through the use of sensors and a chemical dispenser.

Communication

LCD

LCD used to display pH and TDS

Our Arduino will provide real-time feedback on the pH values and Total Dissolved Solids (TDS) values of both the Main Fish Tank and the Clean Water Tank. The idea is to give users an accurate, quick and easy-to-comprehend feedback on the real-time parameters of their fish tank. This solves many issues pertaining to current products aimed at providing such feedbacks such as a universal indicator used to measure a tank’s pH level. Such indicators can be quite difficult to use as it requires the user to compare with a given color reading and does not provide a quantifiable result.

IOt (Thingspeak)

THINGSPEAK interface

Through Wifi connections, our arduino is able to store and plot data over an extended period of time. This allows the user to better able track the conditions of their fish tank and make more decisive decisions on how to better take care of the tank ecosystem. The THINGSPEAK interface can also be accessed at any place and any time.

Water Change cycle

Water Changing animation

StockFeesh utilises a partial water change of 1/4 total main fish tank volume, where we first dispense out 1/4 of dirty waste water in the total fish tank and replace it with 1/4 of clean, treated water. Through this cycle, we will can ensure that the fish will be living in a suitable clean environment.

Key Components

Sensors
- Gravity pH Analog Sensor: Used to detect the pH levels of the main tank as well as the clean water tank
- Gravity TDS Sensor: Used to detect the amount of dissolved solids in the main tank as well as the clean water tank
- Float Sensor: Used to detect the changes in water level in the main tank as well as the clean water tank
Arduino Uno Wifi Rev 2: The brains of the product, in charge of relaying information and activating the water change cycle.
Submersible water pump: Used to transfer water to and fro tanks.
