What is the definition and full form of IoT?
IoT stands for Internet of Things. The devices, physical objects or appliances that are able to share data with each other within a network through the internet are referred to as IoT (Internet of Things). These devices are embedded with sensors, software and other technologies which allow them to collect and share data between each other.
IoT has evolved as another technology ecosystem with the convergence of multiple technologies like ubiquitous computing, edge computing, embedded systems, commodity sensors, machine learning, automation etc. Internet of Things is a mix of electronics, communication and computer science engineering. IoT devices are connected and accessible in a private network because they use firewalls and are encrypted for data security.
Examples of IoT devices in both households and industry today are smart thermostats, smart speakers (Amazon Echo, Google Nest), smart security cameras and doorbells, predictive maintenance sensors on machinery, GPS trackers, smart meters (electric and water) in energy sector etc.
According to IoT Telenor report, the number of IoT devices in production are approaching 14 billion as of now and expected to reach 30 billion by 2025. This is an indication of exponential growth of connected devices in the future. Such a large number suggests there will be a great need for robust infrastructure like 5g and edge computing to handle and analyze data.
Why is it called Internet of Things?
The internet is around for a while, and it has improved communication between people. Everything about the internet was for people so it is referred to as the Internet of people. The new internet is about connecting things, so it is referred to as IoT (Internet of Things). The internet helped people to interact virtually, but IoT (Internet of Things) allowed devices and components to communicate and share information with each other in surroundings.
As internet evolved, it enabled the connectivity for limited electronic devices like smartphones, desktops and iPods but now with IoT (Internet of Things), connectivity is expanded to other electronic devices like air conditioners, doorbells, smart lights and security cameras, smart locks etc. A smart home is a classic example for Internet of Things applications and devices.
IoT devices are classified into to two types:
General devices:
These devices are connected to the internet or a local network using either wired connections (physical cables) or wireless signals (Wi-Fi, Bluetooth or cellular data). The purpose is to connect multiple devices for communication, data exchange and remote control.
Sensor based devices:
These devices are embedded with sensors and actuators. Sensors collects data which is collected from its surroundings and send it to the gateways while actuators perform the actions based on sensor data or commands received.
4 Essential Components of IoT (Internet of Things):
Hardware, data, software and connectivity are the four key components for IoT (Internet of Things) to work efficiently. They are collectively known as IoT ecosystem or IoT Architecture.
Hardware:
These physical components are embedded with sensors and actuators. Sensors capture information from weather conditions, soil moisture, and humidity and send this data to gateways. The data is analyzed in cloud storage and sent back to actuators to perform the actions.
Data:
Data is the key for making informed decisions. Without data, it wouldn’t be possible for IoT devices to analyze, interpret and respond. Example: sensor data create patterns, detect issues and enable automation, allowing IoT system to respond in real-time.
Software:
Software is like the brain of the IoT application. It helps in data analysis, data visualization and data processing. It transforms raw data into actionable insights. Advanced software uses machine learning and artificial intelligence for predictive analytics and automation, making the entire IoT process more seamless, effective and intelligent.
Connectivity:
Internet (wired or wireless) allows physical devices to communicate and share data with the cloud and gateways, making the IoT ecosystem work as intended.
Which sectors are using IoT in 2024?
Industries use IoT (Internet of Things) for operational efficiency, business transformation, predictive maintenance and valuable data insights etc. Some industries which are leveraging IoT are named below:
Manufacturing:
Healthcare:
Smart hospitals are using IoT devices for monitoring vital signals, and patient health conditions remotely.
Automotive:
IoT enabled vehicles provide real-time traffic updates and optimize fleet management that results in efficiency and cost control.
Retail:
IoT gathers data from various connected devices and analyzes customer behavior, preferences, and in-store experiences to improve marketing strategies.
Agriculture:
IoT sensors track the environmental changes and send data to information centers. The necessary actions are taken by actuators based on the real-time data. Drip irrigation is a classic example.
Energy:
IoT enabled smart grids monitor energy consumption. It helps in reducing power outages and enabling renewable energy integration.
The future of IoT is more likely to expand across several industries improving connectivity and automation in everyday life. IoT with the integration of advanced AI and 5G has potential to communicate faster and smarter to provide more actionable insights. IoT in future will create more smart cities, more efficient industries and revolutionize the healthcare.
