Internet of Things & Top Devices of 2019 You Should Know!

Currently, approximately more than 7 billion humans are living on this planet but to your surprise, by 2020, there will be over 20 billion IoT devices. Its production and usage have significantly increased in recent years and some of the most widely top IoT devices include smartwatches, smartphones, smart gadgets and smart vehicles.

IoT or internet of things is a concept which was first introduced about 20 years ago but it is now when this cool technology is making headlines throughout the world. Whether it is connectivity, smart devices, sensors or any other, everyone is talking about the usefulness of IoT.

This technology is now present everywhere from your house to car to office. If you will trust the numbers then in 2015, there were around 1.41 billion connected devices and by 2019 this number jumped to 26.66 billion IoT-based devices. And by 2025, it is expected that there will be over 7 billion connected IoT devices.

So, what are these devices?

Connected devices are around for decades, for example, any PC is a connected machine but is not an IoT device, however, you can say that an IoT is something which is connected via an internet connection.

In very simple words, anything or device which uses the internet for making connections and responding to other devices, people, or systems can be called the Internet of Things or IoT.

These devices support the expansion of internet connection beyond the standard devices which we usually use such as laptops, computers, mobiles, tablets and so on. IoT devices are purely integrated with high definition technology which allows them to communicate or interact over the internet in a smooth fashion. It can be managed and controlled remotely whenever required.

Some of the common technologies which are used in these devices are low energy wireless, NFC, LTE, Bluetooth, ZigBee, wireless protocols and others.

More about these Devices…

IoT-Internet of Things

Any normal device can be transformed into smart IoT devices based upon 2 criteria. First, the device must have the capability to connect with the internet and second, the device can be integrated with other technologies like sensors, functional software and others which support network connections and actuator.

Both of the functionalities are the main ingredient of any IoT device. For instance, earlier, watches were used to see time and date but now, with smart IoT devices, any user can check heartbeat rate, calorie count, the total number of steps walked in a day and so on.

Despite all these informations, these devices have both advantages and disadvantages.

Advantages of IoT devices

Of course, there are several advantages of these devices which are as follows:

  • It encourages the interaction between devices which is also called machine to machine interaction
  • Provides good automation and control
  • Better to operate
  • Saves time
  • Includes strong monitoring features
  • Allow users to save money by reducing the manual task
  • Can automate daily tasks
  • Increases efficiency and ultimately saves more time
  • Makes a better quality of time

Disadvantages of IoT devices

As every good thing has its downsides too, IoT also comes with certain disadvantages. Some of its demerits are as follows:

  • These might become highly complex which will result in failure.
  • High chances of security breaches and these devices are more likely to affect user privacy.
  • Less safe for users
  • Reduction in manual tasks might result in job reductions.

Among many, some of the widely used IoT devices are smart mobiles, smartwatches, smart refrigerators, smart door lock, smart bicycle, a smart fire alarm, smart security cameras or systems, and smart fitness trackers.

Internet of Things and the Security Issues


As of now, almost all or the majority of IoT devices have some or other kind of security issues and it has become one of the biggest problem considering its tremendous use. And the worst part is that no one actually knows how to deal with this.

Any hacker can easily breach any IoT device and can spy its owners. Above that, they can control industrial devices, systems, manipulate production lines, can cause factories to shut down and even be responsible for shipwrecks. These are not just the speculations but in real-world several instances have already been occurred like shutting down electrical grids and so on. A simple looking hack can turn any IoT device into a spying tool or medical device can also be compromised which can jeopardize several lives.

In the near future, the numbers of these devices are expected to increase by several folds and with this, the stakes get higher with pressure building on all the companies to solve this problem.
