1.1 Key Characteristics
Connectivity: IoT devices are connected to the internet, allowing them to send and receive data. This connectivity enables real-time communication and interaction between devices.
Sensors and Actuators: IoT devices are equipped with sensors that collect data from their environment, such as temperature, motion, or light. Actuators enable the devices to perform actions based on the data collected.
Data Analytics: The data collected by IoT devices is analyzed to generate insights and inform decision-making. Advanced analytics and machine learning algorithms can identify patterns and trends, leading to actionable intelligence.
1.2 How IoT Works
Data Collection: IoT devices use sensors to collect data from their surroundings. For example, a smart thermostat might measure the temperature of a room, while a fitness tracker monitors a user’s physical activity.
Data Transmission: Collected data is transmitted to a central system or cloud platform via the internet. This transmission is often facilitated through wireless communication technologies such as Wi-Fi, Bluetooth, or cellular networks.
Data Processing: The transmitted data is processed and analyzed to derive meaningful insights. This processing can occur on the cloud or locally on the device, depending on the application and requirements.
Actionable Insights: Based on the analysis, actionable insights are generated. For instance, a smart irrigation system might automatically adjust watering schedules based on weather data, or a connected car might alert the driver to maintenance issues.
