How IoT ( Internet of Things) works ? Step by step process explained

Have you ever wondered that what will happen if your music system, bread toaster, washing machine, TV, juicer, car i.e. almost all of your electronic devices are connected to each other and can talk!! Well yes, literally! What will happen then? Welcome to the world of internet of things !

What is IoT

As per the wikipedia, the Internet of things is the extension of Internet connectivity into physical devices and everyday objects.


Despite this simple definition many are not able to understand the process involved in IoT.  There are many articles on Google explaining its pros and cons but only a few are explaining its process.

So being a tech blog we though it is our responsibility to make you understand IoT in the simplest form if you have not understood the definition than simply go through the step by step process involved in IoT mentioned below.

The steps involved around IoT

1. Data Ingestion

IoT devices/sensors collect data from the environment. The data can be as simple as temperature/humudity or it can be as complex as a full video feed.

The data needs to be sent to the cloud to be analyzed. But it needs a way to get there.

Almost 5 quintillion bytes of data produced every day by IoT devices

2. Data Transmission

The data is transmitted to the cloud via Gateways (Telemetry Devices), The gateways use both the cellular as well as the satelite communication to transmit the data.

To ensure data security, protocols such as Bluetooth, Sig Fox, LoRa, NB-IoT, ZigBee, COAP, REST, DDS, MQIT, XMPP, etc. are used

3. Data Processing

Once the data gets to the cloud, IoT platform processes it. The processing can be as simple as checking if the temperature is within the acceptable range or it could be very complex, such as using computer vision on the video to identify objects.

4. Data Visualization

The processed data (Information) is made to the end-user by providing alerts to the user (E-Mails, text, notification). The user might have an application (interface) that allows him to proactively check-in to the system.

5. Data Analysis and prediction

To utilize the data collected over the time, data analytics makes use of the historical data to provide actionable insights. Insights help in predicting future events that may occur.

You  can make intelligent business decisions based on the insights and predictions generated from the data.
