The latest data received from the Aquarium is shown to keep the global state of the system under control. If an error has occurred here you can check the parameters out of the range.
The temperature of Aquarium must be taken under control because fish and plants cannot live in a too hot environment. If the temperature rises too much, the system should start some fans up to make the water cooler.
The water acidity is a parameter that shows the health of the Aquarium. If everything works correctly pH should be about 7.
Since the water evaporates it is important to provide an amount of extra water every day to keep the water level constant. This parameter shows the level of the tank under the Aquarium to know when the water stock has run out.
Some RGB leds replace the solar light and provide plants with the necessary energy to the photosynthesis. We can set sunrise and sunset times to manage the alternation of day and night.
If the temperature grows too much, some fans improve the evaporation rate and the heat exchange, thus cooling the water.
The carbon dioxide rate is important for the plants photosynthesis. During the day CO2 must be added to increase oxygen production while during the night the plants produce it.
The potassium is used as fertilizer for the plants and must be added every day to maintain the amount of vegetation necessary for the fish life.
