An IoT device refers to a product connected to the Ethernet. You can use an Ethernet-connected product for the project shown below.

We can recreate this project by connecting the Ethernet to existing devices generally used for home automation, smart factory, or smart city.

So, if you ask the question, “Is IoT simply connecting the Ethernet to a device?”, the simple answer is “Yes”.


IoT is made up of a large network, which can be used to for home automation leveraging few sensors even in an old home.

You can also create a Smart Factory with just a few sensors. Think about what kind of sensors you plan to use the most!

Essentially, various sensors are used to form one large system and sold for commercial purposes.

However, one independent program is required to monitor and control the values of each sensor in such a large system.


That is where the Cloud comes in. The Cloud has a large repository inside, which exists to make it easy to control all the data and sensors.

The meaning of Big Data is closely related to the Cloud.

So let’s look at it this way – inside an IoT system, there is a big store (Big Data) called the Cloud.


You can easily find several free or partially paid Cloud systems from Daliworks such as Thing+, Blynk(App), or Ubidots.








Simply introducing Thing+, it can use multiple sensors for actual commercial use.

Ubidots is free; however, its database does not exist so it is hard to utilize Big data.


Blynk is very convenient because it is linked to an app. But the point system is operated, so if you use all of your initial points, you have to purchase points again.

Usage for each Cloud can be found at
