Internet of Things – Where the web and the physical world meet

The Internet of Things (IoT) is a scenario in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Seems convoluted? Let me break it down for you.

Your electronic device is a ‘thing’ in the Internet of things. Smart locks, smart thermostats, smart cars — you’ve probably heard some of these terms lately, and you’re going to hear them even more as the year goes on. But what are these things exactly — and what makes them so smart? A smart thermostat which is connected to your Wi-Fi will allow you to change the temperature using your mobile phone. This ingenious device can also learn your behavioral pattern to create a temperature setting schedule. As in, it will automatically decrease the temperature once you’re done exercising. The potential value is that you can save money on your utility bill by being able to remotely turn off your air conditioner, which you forgot to do before leaving the house. Smart, isn’t it?


The IoT is wonderfully complicated topic with its application spectrum being infinite. One can envision a scenario where your fitness tracker detects that you’ve fallen asleep and then automatically turns off your TV and lights. Or, before hitting the road, your car could pull up your work calendar and automatically provide the best route to your meeting, or send a note to relevant parties if you’re running late

(Stymied yet?)

On a broader scale, it is being used by cities to monitor things like the number of available parking spaces, air and water quality, and traffic.

So, how does this work? I’ll try not to get too technical here. First, there’s the underlying technology, the various wireless radios that allow these devices to connect to the Internet and to each other. These include more familiar standards like Wi-Fi, low-energy Bluetooth, NFC and RFID, and some that you’ve probably haven’t heard of, like ZigBee, ZWave and 6LoWPAN (have your eyes glazed over yet?)

Then there are the things themselves, whether they’re motion sensors, door locks or light bulbs. In some cases, there may also be a central hub that allows different devices to connect to one another.

Finally, there are cloud services, which enable the collection and analysis of data so people can see what’s going on and take action via their mobile apps.

If you’re starting to dig the sound of this IoT thingamabob, you’d want a few gadgets around. If you’re looking to buy now, as with anything, do your research and make sure you’re getting a solution that is actually going to solve a problem. After all, making sure your kids get home safe from school is one thing, but cooking a pot roast in a Wifi connected crock pot is another.
