IoT | Internet of Things (.io)

Internet of Things (i.e., IoT). Why it is called so, because of the way it works by connecting devices, embedded systems, sensors, and other utilities. Commonly used in industries, hotels, big buildings, even in home. Actually what IoT do, it works like a middle person connecting the input platforms and the output platforms (for example connecting a temperature sensor and widgets to calculate the temperature values). It is the platform used to transfer data wirelessly and range less.

How it works?

It is a simple connectivity of hardware and software. Hardware likes microcontrollers, sensors, GSM, Wi-Fi, Bluetooth and many other modules, on the other hand software like similar to ‘C’ and ‘C++’ which controls and gives data by processing.

 Actual process:

Data collected through sensors -> Goes to the server in IoT platforms -> Devices connected to platforms like computer or smartphones.

And it goes vice versa when a command is given the devices like smartphones at the other end it may connected like light, fan, and sensors, it can be controlled like switching on or off may controlling the voltage levels.

Online platforms

There are many apps and online websites are available which will help to get the readings.

Many options are available in the apps like controller through Wi-Fi, Bluetooth. IoT is effective is depends on where you use and how do you use in such manner IoT is a biggest leading technology.

Simple steps of IoT

·         Register your account in IoT Platforms

·         Connect your project (Hardware components)

·         Connect the project to output device (i.e., smartphone or computer)

·         Then your project works

Basic projects using IoT are (DIY):

·         Switching of light on and off

·         Thief detector

·         Water level of tank

·         Security alarm

·         Fire alarm

·         Bluetooth control car

·         Drones

·         Weather station

·         Speed detector and etc.

 

Applications:

IoT applications are endless. It depends where you use like smart home, smart city, and smart vehicle. They are huge field IoT in Industry, HealthCare, Agriculture, Energy saving, Environmental monitoring, Transportation even in IPL (Smart Stumps).
