DIY Automatic Pet Water Dish

Keeping your pet's water dish full can be a chore (especially if your pet is the large, thirsty kind). Commercial auto-water devices are expensive and don't supply the freshest water. The hacker solution, of course, is to rig your own water-refilling system.

For this project, Avatar-X tapped into his kitchen water supply using a standard refrigerator icemaker hookup, which he connected to an irrigation valve (used for garden watering systems) to prevent water overflow. An Arduino controls the valve and detects the water level via two sensor wires in the bowl.

Schematics and Arduino source code are provided on his website so all you DIYers can create your own system for making sure your pet always has fresh water.

If you try this, let us know how it works out, or feel free to share other pet-related hacks in the comments.

Automatic Dog Water Dish [via Hack a Day]


    You could always apply this same hack to the water reservoir on your espresso machine — get rid of those annoying pre-7am pump malfunctions…

    You can always substitute a larger bowl!

    Our dog was an outside dog (big, hairy german shepherd and he had a large yard so don't jump to conclusions people) and we got this thing at the pet store that you just screwed onto a water tap where basically the dog would just push the little lever and water would come out. Why waste money on random crap when you can just have simple things? No bowl, no problem.
