Explanation

What Is The Internet Of Things? The Internet of Things, or IoT, refers to billions of physical devices around the world that are now connected to the internet, collecting and sharing data. This can be anything from cellphones, coﬀee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of. How Does This Impact You? There are many examples for what this might look like or what the potential value might be. Say for example you are on your way to a meeting; your car could have access to your calendar and already know the best route to take. If the traﬃc is heavy your car might send a text to the other party notifying them that you will be late. What if your alarm clock wakes up you at 6 a.m. and then notifies your coﬀee maker to start brewing coﬀee for you? What is an example of an Internet of Things device? A lightbulb that can be switched on using a smartphone app is an IoT device, as is a motion sensor or a smart thermostat in your office or a connected streetlight. An IoT device could be as fluﬀy as a child’s toy or as serious as a driverless truck.At an even bigger scale, smart cities projects are filling entire regions with sensors to help us understand and control the environment.
