Greetings to all,
when i came with the idea to start SiGAlabs, my mind was basically on my favorite aspect of modern technology which is the upcoming era of Internet of Things!
What is this Internet of Things (IoT)?
In case you haven’t heard about IoT in the past, let me give you a short intro.
The Internet of Things (IoT) is a scenario in which every thing has a unique identifier and the ability to communicate over the Internet or a similar wide-area network (WAN). Things, in this context, can be people, animals, servers, applications, shampoo bottles, cars, steering wheels, coffee machines, park benches or just about any other random item that comes to mind.
Of course there are so much to tell, it’s a fascinating, relative new, world.
As technology becomes “cheaper” and communication modules smaller and easy available to the enthusiast or the independent engineers, more and more smart, low-cost and maybe open source solutions will be available. Following the same path, as machines made the “connection” between people from all over the world a reality the last decades, it’s now time for them to gain some logic and connect to the same network they have created. It’s inevitable! (No, the Skynet is just a movie OK? )
Wireless Sensor Networks and the IoT
Wireless sensor networks (WSN) behave as a digital skin, providing a virtual layer where the information about the physical world can be accessed by any computational system.
As a result, they are an invaluable resource for realizing the vision of the Internet of Things (IoT).
Sure you can have a device connected to the internet sending data to an online IoT platform. But what happens if you want to monitor several sensors spread all over the place.?
Even if you have just every device independent connected to the internet, some of the sensors may need to be outdoor or in different rooms or just moving around.
Here comes the need for a Wireless Sensor Network. WSN networks connected to the internet will surely help to spread out the IoT idea.
Also the cost for a wireless device part of a WSN network must be significant lower from an IoT device to justify its existence.
So, it seems a good idea to use WSN to centralize all sensors data to an internet powered device that will gather the readings and send them to the cloud.
