IoT stands for Internet of Things. It refers to the interconnectedness of physical devices, vehicles, buildings, and other objects that are embedded with sensors, software, and network connectivity, which enables these objects to collect and exchange data.

This allows them to be controlled remotely and to communicate with other devices and systems. IoT can be used in a wide range of applications, such as smart homes, industrial automation, and transportation systems.

Application of IoT

IoT has a wide range of applications across various industries, some examples are:

• Smart homes: IoT devices such as smart thermostats, smart lighting, and smart security systems can be used to control and automate various functions in a home.
• Industrial automation: IoT devices can be used to monitor and control industrial equipment, allowing for greater efficiency and precision in manufacturing processes.
• Transportation systems: IoT technology can be used to track and monitor vehicles, manage traffic flow, and optimize routes for transportation companies.
• Healthcare: IoT devices such as wearable fitness trackers and remote patient monitoring devices can be used to collect and share data with healthcare providers for improved patient care.
• Retail and logistics: IoT technology can be used to track inventory levels, monitor the movement of goods, and improve supply chain efficiency.
• Agriculture: IoT devices can be used to monitor soil moisture, temperature, humidity, and other environmental factors to optimize crop growth and increase yields.
• Energy and Utilities: IoT technology is used to monitor and control energy consumption, and improve the efficiency of power generation and distribution.
• Environmental monitoring: IoT devices can be used to monitor air and water quality, detect pollution, and track the movement of wildlife.

These are just a few examples of the many potential applications of IoT technology.

Basic requirements to develop IoT application

To develop an IoT application, the following basic requirements are generally needed:

• Sensors and actuators: These devices are used to collect data from the physical world (sensors) and to control physical devices or systems (actuators).
• Connectivity: IoT devices must be able to connect to a network, whether it be a local network or the internet, in order to transmit and receive data.
• Device hardware: IoT devices require a microcontroller or single-board computer to process the data they collect and control the actuators.
• Cloud or edge computing: IoT devices typically transmit data to a cloud-based platform or edge device for storage, analysis, and further processing.
• Software: IoT applications require software to control the device hardware, process and analyze data, and provide a user interface.
• Security: IoT devices and systems need to be secure to protect against unauthorized access and data breaches.
• Power source: IoT devices often rely on batteries or other small power sources as they are designed to be portable and low-power.
• Interoperability: IoT devices need to be able to communicate with other devices and systems, regardless of the manufacturer or protocol.
• Scalability: IoT systems need to be able to scale up or down as the number of devices increases or decreases.
• Maintenance and support: IoT devices and systems need to be maintained and supported to ensure they continue to function properly over time
• Programming skills: one must have expertise in any of programming language like Java/Python etc.

The Internet of Things is a term which describes how the different devices connect together to transmit data using the network. 

The IoT is an expansion of a computer network where one can easily use on other devices like home appliances, smart tv’s, fitness trackers, robotics vacuum cleaner, etc.

So far we have been uysing internet on our Personal computer or Laptop or on our smartphones that’s just for the sake of information exchange but IoT gave huge opportunities to explore the use of the internet on other said devices and work become smarter.

7 Main Characteristics of IoT

1) Connectivity: Here devices need to be connected.
2) Things: devices which are designed to be connected.
3) Data: Source of Internet
4) Intelligence: Sensing data using Artificial Intelligence or Data Analytics etc.
5) Action: Where real usage of data takes place.
6) Ecosystem: in community goals, organizational goals, etc.
7) Communication: devices get connected so there is a flow of data between machine to machine (M2M).

Types of IoT

a) Industrial IoT : Improving operational efficiency etc.
b) IoE : Internet of everything like People, process, data etc.
c) CIoT : Consumer Internet of Things like Home appliances, smart Tv’s, etc.

IoT is based on the industry standard of IEEE.

Applications of IoT

Home automation: control and automation of lighting, ventilation, air conditioning, robotic vacuums, air purifiers.

Wearable: smart watches, fitness trackers, VR etc.

Environment: IoT application technologies that have sensors can be used to monitor air and water quality, soil or atmospheric conditions, and even the movements of wildlife.

The IoT devices can also be used in applications such as tsunami early-warning systems to enable authorities to offer more effective responses and aid.

Utilities: real-time grid assessment.

Logistics: real-time visibility of location.

How IoT works
To work IoT, the following are essentials

a) Hardware (to communicate other devices)
b) Protocols (set rules to transmit data)
c) Domains (locations to store data)
d) Applications (software to communicate with devices)
