Story

Urban fish farms are slowly losing attraction and fewer people are wanting to work as fish farmers. This trend has led to a lack of manpower to continue the fish farm industry. The project aims to address this issue by developing an automated fish maid that will not require actual people to be there.

Objective

To design a system to reduce manpower needed to maintain fish farms.
To make sure requirements are met to raise and breed fish.
Achieve the goal of 30% of total food production by 2030.

Research

If water is too dirty, fish will die.
Certain fish eggs don't hatch at certain temperatures.
Decrease in people wanting to work as fish farmer.
Lack of space will cause stress on the fish.

Project

Temperature sensor - It monitors the temperature of the water preventing the temperature from rising too much causing the fish to die. If the temperature is fine, the temperature sensor will go into low power mode. If the temperature rises too high, it will turn on and cool the water down by pumping cool water. If the temperature drops too low, it will turn on and warm the water by pumping warmer water.
Water level sensor - It makes sure the water level in the tank is enough for all the fishes.
Water clarity sensor - Make sure the water is not clouded and dirty so it does not affect the fishes.
