Automatic Pet Water Dish Filler

at 5:33 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


Keeping our cat’s water dish topped up is my daughter’s job but it would be something that would be nice to automate. Only thing I would always be scared about is if a sensor went bad or there was some bad code that caused the thing to run for 5 or 6 hours when I was out… I guess having a limited reservoir size would be one way to limit the potential damage. If you are thinking of automating your Pet Water Dish check out this Arduino based project over at AV Brand.

“I decided it was time to build an automatic water dish that refills itself. I bought an icemaker water hookup (designed to attach the icemaker in a fridge to the water supply) and my friend Frysteev helped me plumb it in. The tiny 1/4-inch water line runs to the top of my kitchen cabinets, where it enters an irrigation valve ($22). This valve then runs to some clear tubing, down from the cabinets and into the water dish. Also in the water dish are two sensor wires, one at the bottom and one at the top of the dish. “
