The internet of things is a hot topic in industry. The idea is products will have sensors, software and connectivity to the cloud which enables the exchange of information between user, product, and manufacturer. Well known examples are the Nest system in homes or smart meters in San Francisco. The education market is starting to play in this field especially in city planning and robotics.
If you are curious to get a glimpse of what the future will look like with IoT enables product systems, I recommend checking out John Deer's Farm Forward video. I love the pacing of the video which combines futuristic technologies with traditional past times. In the classroom this could be a nice hook video to introduce Internet of Things.
