IoT (Internet of Things) refers to the interconnected network of physical devices, vehicles, buildings, and other objects embedded with sensors, software, and network connectivity, allowing them to collect and exchange data with each other and centralized systems over the internet. In essence, IoT involves everyday objects becoming "smart" and capable of communication and interaction.
Key components of IoT include:
Devices and Sensors:
These are the physical objects equipped with various sensors (such as temperature, humidity, motion, or GPS) that gather data from the environment or device itself.
Connectivity:
IoT devices are connected to the internet, either via Wi-Fi, cellular networks, Bluetooth, or other communication protocols, allowing them to transmit data to centralized servers or other connected devices.
Data Processing:
Collected data is processed, often in the cloud, where it can be analyzed, interpreted, and used to derive insights or trigger actions.
User Interface:
Users can often access IoT data through applications or dashboards, enabling them to monitor and control IoT devices remotely.
Automation and Control:
IoT systems can be designed to automate processes and make decisions based on the data they collect. For example, smart thermostats can adjust the temperature based on occupancy and weather conditions.
