High Initial Cost: Implementing IoT systems can be costly for small firms and rural homes.
Complexity: Managing a large network of linked devices takes skill and ongoing maintenance.
Data Overload: IoT creates large volumes of data, causing storage and processing issues.
Access Requirements: IoT devices require consistent Internet access, which can be challenging in remote
regions of India.
Do you know?
IoT technology is used in space exploration, including monitoring the health of astronauts and managing
spacecraft systems remotely.
The International Space Station employs IoT devices to track equipment and optimise operations.
How Data Flow in an IoT System?
In an Internet of Things (IoT) system, smart devices and AI work together to collect, process, and use data
to make life easier and smarter. The process starts with sensors that collect data from the environment, the
user, and smart devices like smartwatches, refrigerators, or cars. This data is then sent to mobile phones,
tablets, or other smart devices, which forward it to cloud servers using the internet. In the cloud, the data
is processed and analysed to understand what is happening in real-time. The results are shown to the user
through notifications, suggestions, or visual displays like graphs and charts. The processed data is also stored
safely for future use. Throughout this process, the system tries to understand the context or situation (called
context discovery) so that it can provide more accurate and helpful responses. This flow of data and smart
decision-making is what makes IoT systems intelligent and useful in daily life.

Examples of IoT Devices
Some of the examples of IoT devices include:
Smart thermostats: Smart thermostats automatically adjusts temperature settings based on your
preferences and behaviour (e.g., Nest).
