“I can tell when my parents start their day and when they’re active. It’s interesting but it doesn’t violate their privacy like cameras would.”

How it Works

CarePenguin Tracks Events of Water Use

The average senior citizen uses water seven times a day!

(Making tea, washing hands, running the dishwasher, etc.)

CarePenguin tracks water use for the purpose of ensuring a senior citizen is up and active. All of these activities indicate a water usage event that’s detectable by CarePenguin and patterns become obvious quickly.

Easy Setup

Takes 5 minutes. That’s it!

CarePenguin easily attaches to the hot water pipe output from a water heater and pairs to WiFi through the CarePenguin app

Safe and easy

Our sensor plugs into a nearby outlet and attaches to the outside of the pipe. No changes in plumbing needed!

Notifications and Updates

If something is wrong, we’ll let you know

If we detect a lack of activity, we’ll notify you and encourage you to check in with your loved one to make sure everything is okay.

Available with CarePenguin Premium
