The Internet of Things (IoT) is changing the way we live, work, and interact. From switching on lights with voice commands to managing entire factories remotely, IoT is everywhere. It connects everyday devices to the internet, allowing them to collect and share real-time data.
As industries adopt more IoT technologies, the demand for professionals with IoT skills is on the rise. Healthcare, transport, supply chains, and smart home devices need skilled engineers to develop, manage, and secure their networks. So, what is IoT exactly, and how can one build a career in this field?
What Is the Internet of Things (IoT)?
The Internet of Things (IoT) refers to a network of devices that connect and communicate through the Internet. These devices can collect, send, and receive real-time data without human intervention. They include everything from smartwatches and smart thermostats to industrial sensors.
The basic structure of IoT involves:
- Sensors: These gather data like temperature, motion, or location.
- Connectivity: Devices use Wi-Fi, Bluetooth, or cellular networks to transmit data.
- Cloud Platforms: Data gets stored and analysed here.
- Automation: Based on the data, the system can trigger actions, like sending alerts or adjusting settings.
IoT devices aim to make systems more energy efficient and responsive. From smart home tech to large-scale industrial setups, their influence is wide-ranging and growing.
How Does IoT Work?
At the heart of IoT lies a mix of hardware and software. Here’s a simple breakdown:
- Sensors and Microcontrollers: These collect data from the surroundings.
- Gateways: They transmit data from devices to the cloud.
- Protocols: Communication happens through standard methods like MQTT or HTTP.
- Cloud Processing: Once in the cloud, analysts analyse the data and make decisions.
- Action and Response: The system might notify users or take automated action.
Behind the scenes, embedded systems work to manage data flow, ensure security, and respond in real time.
Real-World Applications of IoT
| Sector | Examples |
| Smart Homes | Smart locks, lighting systems, and voice assistants |
