Internet of Things (IoT) is presently a hot technology worldwide. Government, academia, and industry are involved in different aspects of research, implementation, and business with IoT. IoT cuts across different application domain verticals ranging from civilian to defence sectors.
Birth of IoT
The term “The Internet of Things” (IoT) was coined by Kevin Ashton in a presentation to Proctor & Gamble in 1999. He is a co-founder of MIT’s Auto-ID Lab. He pioneered RFID (used in bar code detector) for the supply-chain management domain.So, let me first take you through a quote by Kevin Ashton, which he wrote in 2009 for RFID journal.
If we had computers that knew everything there was to know about things—using data they gathered without any help from us—we would be able to track and count everything, and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best.
We need to empower computers with their own means of gathering information, so they can see, hear and smell the world for themselves, in all its random glory.
The above Kevin’s quote would have given you an idea about the ideologies behind the development of IoT.
Introduction to IoT
he ‘Thing’ in IoT can be any device with any kind of built-in-sensors with the ability to collect and transfer data over a network without manual intervention. The embedded technology in the object helps them to interact with internal states and the external environment, which in turn helps in decisions making process.
he Internet of Things (IoT) is expanding at a rapid rate, and it is becoming increasingly important for professionals to understand what it is, how it works, and how to harness its power to improve business. This introductory course will enable learners to leverage their business and/or technical knowledge across IoT-related functions in the workplace.
At this stage we divide our IoT development into two parallel technologies: Wearable and Embedded.
Tizen is fast becoming one of the most popular platform for Mobile and wearable devices. Tizen SDK comes ported with wearable emulator which makes it easier to develop wearable solutions for Tizen platform.
As fifure 3.1 suggests, a large Android Wear devices are now being made and marketed. Smart watches are getting popular by every day. Android Wear apps can be developed and tested in Eclipse. This Android Developer Guide helps you in setting up Android Wear development environment in Eclipse.
Arduino is probably the best starting point for embedded based IoT. Basic Android boards don’t come with Ethernet shield and for Arduino to be able to work as IoT device, you need to select Android with Ethernet shield. You can actually order a basic board of Arduino like Arduino Decimilia or Dueminolova and learn the hardware basics like connecting sensors, working with actuators, serial communication and then you can go for Ethernet shield and look for more web based application for Arduino.
Raspberry Pi is probably one of the best things to happen in DIY IoT. A wide range of Data driven applications like Home Automation Server toHome Multimedia server, File Server can be developed withPi. PI like Arduino has general purpose IO pins. But seamless working with sensors is bit tedious in Pi
Benefits of IoT
Since IoT allows devices to be controlled remotely across the internet, thus it created opportunities to directly connect & integrate the physical world to the computer-based systems using sensors and internet. The interconnection of these multiple embedded devices will be resulting in automation in nearly all fields and also enabling advanced applications. This is resulting in improved accuracy, efficiency and economic benefit with reduced human intervention. It encompasses technologies such as smart grids, smart homes, intelligent transportation and smart cities. The major benefits of IoT are:
- Improved Customer Engagement – IoT improves customer experience by automating the action. For e.g. any issue in the car will be automatically detected by the sensors. The driver, as well as the manufacturer, will be notified about it. Till the time driver reaches the service station, the manufacturer will make sure that the faulty part is available at the service station.
- Technical Optimization – IoT has helped a lot in improving technologies and making them better. The manufacturer can collect data from different car sensors and analyze them to improve their design and make them much more efficient.
- Reduced Waste – Our current insights are superficial, but IoT provides real-time information leading to effective decision making & management of resources. For example, if a manufacturer finds fault in multiple engines, he can track the manufacturing plant of those engines and can rectify the issue with manufacturing belt.
Nowadays, we are surrounded by lots of IoT enabled devices which are continuously emitting data and communicating through multiple devices.
