Fountain for pets Pet Water Warden - a very interesting and useful device, especially if you live at home with a few four-legged friends. The invention consists of a bowl, which are sensors, a water tank, pump and CPU Arduino. From the pump to the bowl of a large water tank is pumped, the level of which is controlled by three sensors which support it at a certain level. Under certain engineering skills this system can be complicated by connecting directly to the tap water bottle system.
