Pi-quarium

Hi everyone, my first major project is a raspberry pi- powered aquarium, I have seen a few people who have done this successfully on the internet from my browsing so far.

Planned functions:
Water Level Sensor
Temperature sensor
Cooling fan control
Control of water exchange
Auto-feeder
Camera for remote monitoring

Project idea:
I’m planning to get an axolotl as a pet and would like a system where I can monitor it and automate the aquarium for when I am out of the house.

One of the best examples I have seen: Example 1

Axolotls like cool water, under 20 degrees c so a temperature control system will be important. Chillers are very expensive and often unnecessary so I’m planning to use a set of 3 large (140mm) fans for evaporative cooling if the water temperature rises above 20.

Being able to automate water changes and switch lighting from a web interface would also make care a lot easier.

Phase 1: Planning and part acquisition
Rasbery pi- x
Case and power supply- x
Order aquarium components-
Fans- Noctua a14 ppc industrial x 3 (need power supplly)
Tank
Sand
Filter
PVC pipe for overflow
Drip filling set

Prototype on fusion 360-

Any thoughts/ Ideas?

Awesome! I would be very interested in seeing your progress. Have always wanted an axolotl, but the level of maintainence frightened me a bit!

PERFECT! Found someone who had made a system using peltier for aquarium tanks, I even have a spare heatsink laying around the house for it! http://www.shine7.com/aquarium/chiller.htm

In my experience of this sort of thing I would have a uv unit in the filter loop
