The heating that listens to your phone
Sam is on the bus. He taps his phone and the heating at home starts. When he arrives, the house is warm.
The heating is not a computer on a desk. It is an ordinary thing that joined the internet. This lesson is about those things.

Things that join the internet
The Internet of Things (IoT) means everyday objects that connect to the internet. They have a sensor to measure something and a way to send the data.
A smart speaker, a doorbell with a camera and a heating controller are IoT devices. In homes this is consumer use. In farms, shops and factories it is business use. A farm might have sensors that report how wet the soil is.
