Did you ever leave the house, and forget to check to make sure that you turned off your stove? Ever wanted to be able to check whether your fridge was working without having to buy a Samsung smart fridge? Here we present “Know It’s Off”: a sensor which you can attach to the appliance of your choosing and reliably receive information on whether the appliance is on or off. You can customize the interface on our website to modify whether or not you receive text message or email alerts after an appliance has been left on for too long. Your information is also completely confidential. Your personal information is stored securely, and is not shared with any outside sources. The ECE team we have been working with this year has their showcase available here: https://eecs.oregonstate.edu/project-showcase/projects/?id=hqlQtQJGQJpwvEyq
