Moisture sensor in dog bowl

There are many aquarium water level sensors which are water safe and can be wired to any of many devices to send an alert. Some cost less than $20 for the sensor itself, although you’d still need the zwave components.

That said, I wouldn’t use them directly in a dog bowl, since the dog might try to play with the sensor.

Instead, you could set up a closed tank reservoir that fills the bowl and put the sensor in the reservoir. The dog couldn’t get to it, and you’d have more time to do the refill.

Interesting alert system idea. Another option, teach dog to bark when water empty :dog:
