Welcome back to the Introduction to the Internet of Things. I'm Richard Augenti and I'll be your instructor for this lesson. In this lesson we're gonna discuss Use Cases with the Internet of Things. One of the big things to discuss right off the bat is a growth in the Internet of Things. It's projected that there will be a growth of 6.4 billion devices connected to the internet to 20.5 billion in 2020. This is actually a conserved estimate in comparison to others which had this number doubled in some cases. So the industry is growing across all industries at a staggering rate. So that also means a staggering job growth across multiple occupations and industries ranging from IT, security, analytics, development, and so on. In our homes we are seeing voice activation systems controlling devices around the house along with making and receiving phone calls.

These devices include LED lighting, HVAC and Air Quality. Smart Homes integrate many Internet Things devices across the homestead, including energy management, security systems, and access control. This diagram is a good representation of the capabilities of Smart Homes. Wearable Technology includes solutions to improve our ability to be efficient, monitor our health, and use for search and rescue. This diagram provides countless ways that wearables are being used. In agriculture we're combining systems to work within unison to share data and intelligence with monitoring soil moisture, weather, and atmospheric conditions to provide a sustainable and affordable future for farmers and the human race. In retail we can monitor inventory in real time and automatically make orders to ensure supplies are maintained, and always ensure the customer is leaving with exactly what they intended to purchase.

Here's one of the many ways the Internet of Things are being used in the medical industry. An accident occurs and the driver is being rushed to the hospital. While in transit, the patient's vitals are being sent ahead to the hospital to monitor in real time, thus enabling the patient to be cared for more immediately upon arrival. Patients can be monitored remotely after a procedure instead of having to make multiple return visits to the doctor for checkups. This adds value back to the life with reducing waste of time on visits and providing security of being monitored for issues in real time. Where is all this heading? Smart cities. In the future, we'll have cities that move from working in independent silos to combining data between different infrastructure systems and governmental departments as a wholistic system.

This will help reduce carbon footprint, reduce utility costs with energy, and ensure sustainability and livability. This last diagram does a great job in summarizing the use of different Internet of Things technologies across most industries. I recommend taking some time to look it over closely. Well that wraps up our lesson on Use Cases with the Internet of Things. Hopefully this provides some good insight into the different industries, our homes, and the future with Smart Cities. Thank you for joining me for this lesson, and I'll see you in the next lesson.
