Analysts are forecasting that by the year 2020 there will be more than 50 billion connected things (devices) and the total revenue from the Internet of things (IoT) will easily surpass $1.5 trillion.
The numbers look phenomenal, but what exactly is IoT? Is it simply things connected to the Internet? Why do connected things matter?
IoT is much more than things connected to the Internet. IoT is about making dumb things smarter by giving them the ability to sense, communicate, and respond. We have five senses—we can see, hear, taste, smell, and touch. Similarly if you add these sensors to things they can do the same as well. For example, using a camera things can see, using a sound detector things can hear, and using a speaker things can talk. There are so many other sensors that things can use to do so much more than us. By connecting these things to the Internet, they can communicate with us, with other things, and the next frontier where they can use artificial intelligence to think as well. There are numerous applications of IoT, but here are a couple of examples to further understand how IoT is being used to improve our lives:
• A wristband with the ability to monitor your vitals. If it finds anything out of the ordinary, it can alert you and your doctor immediately.
• A security system that monitors the premises of your house for any intrusions and alerts you and any security agencies.
