IMMEDIATE MEASUREMENTS

The website can show the latest values collected from the several probes connected to the Aquarium. The data is acquired by ESP32 and sent to RASPEBERRY PI 3 to be processed. The automatic control is performed and the results can be analyzed in every moment.

GLOBAL STATE

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.

TEMPERATURE

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.

ACIDITY

The water acidity is a parameter that shows the health of the Aquarium. If everything works correctly pH should be about 7.

WATER LEVEL

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.

ENLIGHTENMENT

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.

COOLING FANS

If the temperature grows too much, some fans improve the evaporation rate and the heat exchange, thus cooling the water.

CO2 EMISSION

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.

POTASSIUM ADDITION

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.

DATA TREND

All Aquarium data are memorized in a database and are ready to be visualized. Several graphes have been realized to present the trend in a simple visual way.
