Internet of Things

These days, consumers can buy innumerable smart appliances that promise to make our lives easier. But does that mean we should neglect our seemingly outdated non-smart machines just because they can't send a push notification?

Here we'll discover ways to build a smart IoT system that sends alerts about the state of any appliance from a binary sensor. In one example I'm attaching SW-420 vibration sensors to the back of a washer and dryer to enable remote notification based on laundry room activity. In the next example we're going to build on this core functionality of sending a notification based on state but we'll use a Current Transformer (CT) sensor instead of the SW-420.

While this guide talks about washer and dryer units, this concept may be applied more generally to other appliances.
