The Internet of Things (or
IoT), at the simplest level, are devices which send
and receive data via the internet without the necessity of human intervention.
The Internet of Things (IoT),
is a phrase that was people began using in the late 1990s (). It is the process of making a standard
unconnected device into a ‘smart’ device which gives it the ability to transfer
data over a network from machine to machine.
One of the first IoT devices was a Coca-Cola
vending machine developed in 1982 when a group of innovative computer
science students at Carnegie Mellon University in
Pittsburgh, Pennsylvania wanted to know the stock levels of their local Coca-Cola
machine. To do this they installed micro switches that relayed
the stock levels on the machine’s racks and also reported whether the freshly
loaded drinks were cold yet. This was developed due to their frustration as
they previously had to keep checking the drinks by walking to the machine until
they reached a cold enough temperature for them to drink.
general, there are four main parts of an IoT system. There is the Device, The
Local Network, The
Internet and Back-end
The Device – the device that is to be connected
to the IoT e.g. a Smart Thermostat.
The Local Network – this translates proprietary
communication protocols to Internet Protocol.
The Internet – in simple terms, a global network of computers.
Back-End Services – enterprise data systems, computers
and mobile devices.
and objects with built in sensors are connected together in the Internet of Things
platform, which combines
data from various devices and applies analytics to share the most valuable
& useful information with applications that are built to address specific requirements.
These platforms can filter out what information the relevant material from the irrelevant.
This information can then be used to detect possible problems before they occur,
make recommendations and detect patterns. This can be useful for DNA Sequencing
and making possible DNA solutions for diseases like Genome Therapy.
are many current applications of IOT technology, including smart home devices,
smart watches, connected fitness trackers and even in the workplace.
In the workplace, there are many applications
for IoT devices such as automated data collection, accurate analysis and help
people make informed decisions. Machines is much better at data collection then us humans as
they can collect data much quicker, with 100% accuracy on a much wider scale
and frequency. Before IoT connected sensors and wearables, data had to be
collected manually walk-through studies and surveys. Results of course were
inaccurate and the frequency of data was limited to budget and time.
IoT-enabled devices can be programmed to collect data as frequently as wanted,
which can be used for multiple purposes across the business.
In the future, I believe IoT devices will be
common place within our daily lives. We will live in a connected home and our
vehicles will be connected. When we go to do shopping, there will be smart IoT
beacons around the store which can identity you and give your recommendations
on which products to buy and send vouchers to your mobile devices.
There are also many benefits from this
technology. If there is a person who has mobility issues, they could control
devices across the house with a mobile device or even their voice. This could
be especially helpful in an emergency as they could contact the emergency
services or family from anywhere in the house.
As with any other networked device, there is
a possibility that the device could be hacked if security procedures have not
been put in place. For example, if someone was in range of your Wi-Fi network
and managed to crack your password, they could potential control all of your IoT
devices. This could potentially be very dangerous depending on how many and
which devices that you have installed. If you had some sort of smart air
filter, for example, they could make it malfunction and cause it to poison the
In the future car manufacturers will
implement IoT technology into their vehicles. This will allow the cars to be
receiving updates to keep up to date. This also creates a vulnerability as
hackers could intercept the signal and cause the vehicle to respond in a
