Arduino-ize Your Pool with ARDUPOOL
Diego Gomez has designed an open source device that dispenses chemicals and controls your pool's filtration system.
Swimming pools can be a lot of fun, but they’re a lot of work as well, requiring the addition of chemicals, filtering the water for leaves and debris, and other more intermittent time-consuming tasks. To help “keep your pool under control,” engineer Diego Gomez created ARDUPOOL as a modular open source pool controller.
The device, now funding on Kickstarter, is recommended for pools up to 60 cubic meters, and can use up to four peristaltic dosing pumps to provide your pool with the chlorine, flocculant, algicide, and whatever else it needs to stay “healthy.” It can also control the filtration system of your pool, and features an internal clock to keep things on track after a power loss.
As you would suspect from its name, ARDUPOOL runs on an Arduino Mega, with user interface provided by three input buttons and a small LCD panel. Depending on your configuration, the device can either run a set program or sample the water to regulate dosage based on existing pH and chlorine levels. Further work-in-progress functionality includes a mobile app and even the ability to change the pool's lighting. Of course, as an open source project, you’d be free to add even more features as you see fit.
Reward level pledges run from around $176 to $472 US, with estimated delivery between October 2020 and January 2021.
