What is IoT?

The Internet of Things (IoT) is the network of physical objects/things are embedded with software, sensors, and hardware boards to create a network to gather and exchange data.

Internet of Things is a combination of following:

Sensors and Actuators:

This part estimates a physical amount, for example, sound, temperature, moisture etc. and changes over it into an data to make the system understand and act as needs be.

IoT Gateway:

Iot gateway is used to receive signals from sensors and upload to the network using different communication medium such as LAN, Wi-Fi, GPRS and LoWPAN etc.

Cloud server:

The data transmitted through gateway is stored & processed securely within the cloud server and used to perform intelligent actions that make all our devices Smart Devices.

Mobile apps:

Mobile apps will help end users to control and monitor their devices from remote locations.

Application of IoT:

IoT Sensors:

Hardware Platforms:

Arduino, NodeMcu ESP8266, Raspberry pi, Adafruit, LinkIt One and Intel Edison

Arduino (https://www.arduino.cc/)
ESP8266 (NodeMcu) (https://www.nodemcu.com/index_cn.html)
Raspberry Pi (https://www.raspberrypi.org/)
Linkit One (http://wiki.seeedstudio.com/LinkIt/)
Adafruit (https://www.adafruit.com/)
Intel Edison, etc.

IoT Cloud Platform:

What is Cloud?

In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive.

When you store data on or run programs from the hard drive, that's called local storage and computing. Everything you need is physically close to you, which means accessing your data is fast and easy, for that one computer, or others on the local network.

For it to be considered "cloud computing," you need to access your data or your programs over the Internet, or at the very least, have that data synced with other information over the Web.

Service Models:

Service Models are the reference models on which the Cloud Computing is based. These can be categorized into three basic service models as listed below:

Infrastructure as a Service (IaaS)

IaaS provides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc.

Platform as a Service (PaaS)

PaaS provides the runtime environment for applications, development & deployment tools, etc.

Software as a Service (SaaS)

SaaS model allows to use software applications as a service to end users.
