【Open Source】Nextion smart fish tank project

THIS PROJECT NEEDS UPDATED FishTank_v0_32.HMI (download) with Editors v0.39+


I still remember there is a nice project is posted on the forum a month ago.Do you remember it?

And after a month,I show you something here.

The smart fish tank is consisted of six sections, a main display section, and 5 functions sections, including time setting(Time), pump (Pump), feed (Feed), light (Light) and ultraviolet (UV).

Fish tank project.
Sous Vide?


@Bspranger Yes,it is!

Nextion Fish Tank Project from ITEAD on Vimeo.

The project github link: 

What kind of temperature sensor are you using?

Do you deliver the Rboard Pro for this

Rboard Pro is base on MEGA2560, 4 channel relays,more I/O output. From the bom list on github, you can see a BLE module and a wifi module,which are added for this project.But the final Rboard Pro has not been confirmed yet.

If I use an Arduino Mega 2560 board then the display pages and buttons are not working.

How can I use an Arduino board for this?

one arduino mega2560, four relay models, one DS18B20 sensor,one Nextion display.


I found you must use a extern Power unit and disconnect the USB to the arduino megaboard is this correct.

When I use both the display is not responding for touch.

here is a step by step tutorial of the basic fish tank:

Hi every one.

I am also endeavoring to build a smart Aquaruim controller named JAqua. All is still work in progress. Planning to use the following hardware:

1. Arduino Mega 2560

2. Nextion 4.3" HMI

3. 3 x temp sensors - 2 x normal DS18B20 temp sensors, 1 x DHT11 temp and humidity (For ambient temp)

4. Analog PH Meter

5. 2 x Ultra sonic sensors

6. Relays - 8 ch future expansion to 16ch

7. Indication LED

8. Alarm
