What is IoT (Internet of Things)?
IoT refers to a network of physical devices embedded with sensors, software, and connectivity features that allow them to exchange data over the internet. These devices can include anything from smart thermostats and wearable devices to industrial machinery and autonomous vehicles.
What are IoT Use Cases?
IoT Use Cases are real-world applications in which connected devices collect data, transmit it over networks, and trigger automated or human-driven actions.
These systems combine:
- Sensors and smart devices
- Connectivity layers (Wi-Fi, 5G, LPWAN)
- Cloud and edge computing systems
- Analytics and automation software
They solve operational problems like monitoring, prediction, and automation across industries.
How IoT systems work
IoT systems work through a layered structure that moves data from devices to applications in real time. Each layer handles a specific function to ensure fast, reliable, and scalable data processing.
This IoT architecture collects data from connected devices, processes it through network and edge systems, and delivers insights through cloud-based applications. It enables real-time telemetry processing and low-latency decision-making.
Here are the key layers of an IoT system:
- Device layer: Sensors and smart devices collect raw data like temperature, motion, and machine activity.
- Connectivity layer: Data moves through protocols like MQTT, HTTP, and 5G to central systems.
- IoT Gateway layer: IoT gateways act as intermediaries between devices and cloud systems. They filter, aggregate, and translate data from multiple devices before sending it to edge or cloud platforms.
- Edge layer: Local devices process data instantly to reduce delay and enable quick actions.
- Cloud layer: Cloud systems store large data sets and run analytics for insights and predictions.
- Application layer: Dashboards and apps show data and help users monitor or control systems.
IoT systems collect data from devices, transmit it over networks, process it at the edge or in the cloud, and present insights through applications for real-time decision-making.
