What do you think of when you hear the word pool? If you’re like most people, the word conjures up images of a simple water-filled hole in the ground, perhaps with a few fish thrown in for good measure. But not [Anders Johansson] – his pool is a technical marvel, using more unique pieces of hardware and software than many of the more traditional projects that have done these projects over the years.
In fact, this is one of those projects that is so large in scope that no summary published here can do it justice. The aptly named Poseidon project consists of a number of modular components, ranging from an automated fish feeder to a variety of sensors to monitor the condition of the water itself. How many other ponds can their current water level, pH, and oxygen saturation exceed MQTT?
[Anders] has provided schematics, 3D models, and source code for all the various systems incorporated into the pool, but it’s in the documentation that this project really shines. Each module has its own detailed write-up, which should give you more than enough guidance should you want to recreate or remix what he’s put together. Even if you only use one or two of the modules he’s put together, you’ll still be ahead of the crews who have to maintain their pool the old fashioned way.
In the past we’ve seen projects that tackle some of the individual elements that [Anders] has developed, such as 3D printed fish feeders, but after searching through the archives we can’t come up with up to anything even half as ambitious as Poseidon. At least, not for pools. It reminds us of a highly developed aquaponics arrangement, and we wonder if that might not be a possible outcome of the core project in the future.
