Core Concepts of IoT

Connected Devices/Things: IoT revolves around physical objects or devices, often referred to as “things,” that are embedded with sensors, actuators, and connectivity capabilities. These devices can range from everyday objects like smartphones and wearables to industrial machines, smart home appliances, and environmental sensors.
Sensors and Actuators: IoT devices are equipped with sensors to detect changes in their environment and gather data. Actuators enable devices to perform actions based on the data received. For example, a temperature sensor in a smart thermostat can collect data, and the actuator can adjust the temperature accordingly.
Connectivity: IoT devices use various communication technologies to connect to the internet and transmit data. Common connectivity options include Wi-Fi, Bluetooth, Zigbee, RFID, cellular networks, and LPWAN technologies.
Data Collection and Transmission: IoT devices continuously collect data from their environment through sensors. They then transmit this data to cloud-based platforms or edge computing systems for further processing and analysis.
Internet/Cloud Connectivity: IoT devices communicate with cloud-based platforms to store and process data. Cloud connectivity allows for centralized data storage, real-time processing, and access to remote services.

IoT Applications and Use Cases
