Finally. After a long time building the hardware and the software, the Neptune module is the final module to be added to the Paludarium.
This module is a more complex version of the Apollo units that live inside the Canopy that control lighting and fans. The Neptune module has some control for lighting (namely the underwater lights), but its main purpose is controlling pumps and valves, and measuring back sensors in the paludarium.
For now the Neptune module is setup in the cabinet under the Paludarium:
The unit has been running for over two weeks now without a single flaw… I must be doing something right 😉
