What is the Internet of Things (IoT)?
Defining IoT
The Internet of Things (IoT) refers to the network of physical objects—”things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. These “things” can range from simple household items like smart thermostats and lighting systems to sophisticated industrial tools like robots and heavy machinery.
How IoT Works
IoT systems generally operate through a few core components:
- Devices: These are the physical objects with embedded sensors, actuators, and communication hardware.
- Connectivity: IoT devices connect to the internet or other networks using various technologies like Wi-Fi, Bluetooth, cellular, or LoRaWAN.
- Data Processing: Data collected by devices is sent to a processing platform, which could be in the cloud or on-premise. This platform analyzes the data to extract valuable insights.
- User Interface: A user interface, such as a mobile app or web dashboard, allows users to interact with the system, control devices, and view data.
