2. What is IoT (Internet of Things)?

Kevin Ashton, in a presentation to Proctor & Gamble in 1999, coined the term “Internet of Things“. Almost all, every area, every device, every sensor, every software are connected to each other. The ability to access these devices through a smartphone or through a computer is called IoT. These devices are accessed remotely. IoT is basically a platform where we connect everyday things embedded with electronics, software, and sensors to the internet enabling them to collect and exchange data. In this way, each of your devices will learning from the experiences of other devices, just as humans do. With IoT, the interdependence in the human will expand- i.e to interact, collaborate and contribute to things. The ‘Thing’ in IoT can refer to any device that might comprise any kind of built-in-sensors with the ability to collect and transfer data over a network or internet without manual intervention.

Do you know about IoT Technology and IoT Communication Protocols

For example, an Air Conditioner’s sensor can gather the data regarding the outside temperatures, and accordingly adjust the Air Conditioner’s temperature to increase or decrease it with respect to the outside climate. Similarly, your refrigerators can also adjust its temperature accordingly. This is how devices can interact with a network.

a. How IoT Works?

The entire process starts with the devices themselves, such as smartphones, digital watches, electronic appliances which securely communicate with an internet of things platform. IoT platform collects and combines data from multiple devices and platforms and applies analytics to share the most valuable data with applications to address industry-specific needs.

Let’s start with a simple real-life example- a car after taking a long road trip, Rajesh notices that his check engine light and finds that it needs to look by a mechanic, but doesn’t know if there is something minor or serious. As it finds out, the sensor that triggered the check engine light monitors the pressure in the inner break line. This sensor is one of the many sensors present in the car which are constantly communicating with each other.

A component called the diagnostic bus gathers the data from all these sensors and then passes it to the gateway in the car. The gateway collects and sorts the data from different sensors. This way only the most relevant diagnostic information will transmit to the manufactures platform.

Before this connection to happen, the car’s gateway and platform must register with each other and confirm a secure communication. The platform keeps on constantly gathering and storing information from hundreds of cars worldwide, building a record in a database. The manufacturer has added rules and logic to the platform. The platform triggers an alert in his car, after sensing the brake fluid has dropped below the recommended level. The manufacturer then sends him an appointment for servicing of his car, and the car’s problem is rectified.

IoT Tutorial – Features of Internet of Things

  • AI – IoT technically makes things smart, meaning that it enhances different aspects of life through proper usage of that data, networks, and algorithms. This can range from something as simple as improving or enhancing your refrigerator by embedding it with sensors that automatically detect when milk and eggs run low, and to then place an order with your choice of the grocer to automatically send them over.

  • Connectivity – The notion of networking doesn’t always have to restrict to large networks, it can also exist on a smaller and cheaper scale without compromising its efficiency. IoT comes into the picture and creates these small networks between its system devices.

  • Sensors – The true essence of IoT would not hold effective or true without sensors. They are basically the reason and the crux of why this technology stands out. They play a major role in defining boundaries of IOT by converting it from a passive to an active network.

  • Active Engagement – Today’s interaction between different connected technologies happens through passive engagement. IoT sets a new example by bringing in active content, product, or service engagement.

  • Devices – Devices are more powerful, cheaper and smaller over time, Internet of Things purposely makes use of small devices to deliver its scalability, versatility, and accuracy.

  • Healthcare Application: These days we have digital watches and fitness monitoring devices that have changed the ways of healthcare monitoring. People can now monitor their own health at regular intervals of time. These days if a person is being rushed to the hospital by an ambulance, his/her healthcare statistics are already given to the doctor, and the treatment gets started well in time. Data collected from different patients is now being put to use for the cure.

  • Energy Applications: The energy rates have become paramount. All Individuals and organizations, both are searching ways to reduce and control the consumption of energy. IoT provides a way to monitor energy usages not only at the appliance-level but also at the grid level, house-level or even at the distribution level. Smart systems such as Meters & Smart Grids are installed at various organizations to monitor energy consumption.

5. Advantages of IoT

Because IoT allows devices to remotely control across the internet, it has created opportunities to directly connect and create a link between the physical world to the computer-based systems by using sensors and internet. The interconnection of these multiple embedded devices will result in automation in different fields thereby enabling advanced applications. This would then result in improved accuracy, efficiency along with very less manual intervention. It encompasses technologies such as smartphones, smart meters, smart grids, smart homes, intelligent transportation and smart cities. Now, let’s discuss the major benefits of IoT, in this IoT Tutorial:

i. Improved Customer Engagement

IoT improves customer experience by automatically detecting problems and improving the action. For e.g. as we discussed above, how an issue in Rajesh’s car automatically detect by the sensors. The driver, as well as the manufacturer, will get notified about it. Till the time driver reaches the service station or a mechanic, the manufacturer will make sure that the faulty part is available at the service station and the problem is rectified.

ii. Technical Optimization

If the technology is great, the experience is bound to great. IoT has played a major part in improving technologies and making them better. While we explain in our example, the manufacturer can collect data from different car sensors and analyze it to improve its design and make them much more efficient.

iii. Reduced Waste

With the latest technology, IoT provides real-time insights on crucial problems leading to effective decision making & management of resources. For example, if a manufacturer finds fault in engines of multiple cars, it might give him an insight on major fault and he can track the manufacturing plant of those engines and can rectify the issue with manufacturing belt.
