Imagine a scenario where your home can communicate with you even if you are at work or on vacation abroad. It tells you that a light bulb needs to be replaced or it’s time for your laundry. If you think that this is a scene from a very distant future, then you are mistaken. IoT, or the Internet of Things, is making this a reality. Many technological companies, such as NCS, are already leveraging IoT to create innovative and secure IoT solutions.
For example, IoT-enabled devices can detect air pollutants in a city and alert citizens about potential health hazards. It can be used for smart home automation where IoT-connected devices like smart thermostats provide users comfort, security, and convenience. IoT can also be used for predictive maintenance of machinery, preventing any potential breakdowns before it happens. But what exactly is IoT?
What Is IoT?
The Internet of Things, or IoT, is a network of physical devices or objects embedded with electronics, software, sensors, and connectivity. This allows them to collect and exchange data. IoT technology enables these objects to connect and share data over the Internet, making it possible to monitor and control them remotely.
A smart home is a typical example of an IoT application where intelligent devices such as thermostats, security cameras, and lighting controls are connected and can be controlled remotely using a smartphone or tablet. Other typical IoT applications include wearable fitness trackers, smartwatches, connected cars, industrial equipment, and security systems. With the rapid growth of the Internet of Things, the number and variety of devices that use it constantly expand.
How Does IoT Work?
A combination of hardware, software, and connectivity enables the interconnectivity of IoT devices. IoT devices contain embedded technology such as processors, sensors, memory, communication protocols, and power supplies, allowing them to interact with each other over the Internet. IoT applications use cloud computing technology to store and analyse data collected from IoT devices allowing users to monitor and control their IoT-enabled products or services remotely.
IoT platforms provide a standard interface for connecting multiple IoT services, including device management, analytics, and data visualisation. IoT systems also employ machine learning algorithms, allowing them to learn from the data they collect to make smarter decisions about best operating the connected devices.
To better understand how IoT works, it is best to examine in detail how IoT works within a smart home. IoT enables users to control their lighting, security systems, heating and cooling, appliances, and entertainment systems from anywhere in the world. IoT devices such as smart light bulbs are connected to an IoT hub that connects to the Internet. The IoT hub then sends commands based on inputs from the user’s smartphone or tablet over the Internet back to the IoT hub.
The IoT hub will then send commands to the IoT-enabled devices, like turning on or off a specific light bulb or unlocking a door through wireless communication protocols, such as Wi-Fi or Bluetooth.
The Uses of IoT in Different Sectors of Society
IoT has become pervasive in many sectors, including the industrial sector, healthcare, agriculture, transportation, retail, and education.
IoT enables factories to become more innovative by connecting machines, sensors, and industrial control systems over the Internet. IoT applications would allow companies to monitor machinery performance in real-time and make data-driven decisions to optimise efficiency and reduce costs.
IoT is transforming healthcare by enabling remote patient monitoring and improved diagnosis. IoT devices such as pacemakers can be monitored remotely by doctors, allowing them to keep track of a patient’s health without having to conduct regular visits.
IoT technology is also used in agriculture to improve crop yields and food safety. IoT-enabled sensors are utilised for soil monitoring so farmers can adjust their practices accordingly for maximum productivity. Similarly, IoT temperature monitors help reduce food waste by ensuring that food items are transported and stored at the optimal temperature. An example of IoT usage in agriculture is integrating satellite images of dry crop areas that can predict drought and advise farmers on appropriate harvesting time.
IoT is also used in transportation to improve safety, reduce maintenance costs, and increase operational efficiency. IoT-enabled sensors are placed inside vehicles to monitor performance, detect signs of failure, and enable predictive maintenance. IoT-enabled traffic systems assist drivers with navigating through congested roads and avoiding accidents. Companies with transportation fleets can effectively monitor their drivers’ performances and road safety.
IoT technology is used in retail stores to enhance customer experiences by providing personalised product recommendations or helping customers quickly locate products within the store. IoT-enabled shelves provide customers with information about prices, availability, and other product details without having to ask a store associate for help. IoT technology is also being used in warehouses to track inventory levels, monitor temperature, and ensure that items are stored safely.
The rise of IoT allows educational institutions to improve safety and security. IoT-enabled sensors are placed on doors, window locks, and other access points to detect unauthorised personnel or potential intruders. IoT technology is also used in classrooms to monitor air quality, temperature, and humidity levels for better comfort.
Overall, IoT has the potential to revolutionise many sectors of society by making them more efficient and enabling users to access real-time data at all times. IoT devices allow people to stay connected with their homes, vehicles, offices, factories, and stores while providing valuable insights into their operations. By leveraging IoT technology, people can optimise systems across various industries and make informed decisions based on the data collected from connected devices.
