Study Notes

Introduction to the Internet of Things (IoT)

The Internet of Things (IoT) describes a system of interconnected physical objects embedded with electronics, software, sensors, actuators, and connectivity, enabling data collection and exchange.
These interconnected devices range from everyday objects (appliances, vehicles) to industrial equipment and wearable technology.
Devices communicate with each other and the cloud, enabling automation, data collection, and real-time analysis.

Key Characteristics of IoT

Connectivity: IoT devices connect to the internet and networks for communication and data exchange.
Sensors and Actuators: Sensors gather environmental data (temperature, humidity, location) and actuators control actions (turning lights on/off, adjusting temperature).
Data Collection and Analysis: IoT systems collect and transmit data from various sources for insights, process optimization, and decision-making.
Automation and Control: Devices automatically perform tasks based on rules or real-time information.
Interoperability: Devices from different manufacturers should communicate seamlessly for a functional IoT system.

Technologies Enabling IoT

Wireless Communication Protocols: Various wireless technologies (Wi-Fi, Bluetooth, Zigbee, Cellular, LPWAN) connect devices to the cloud.
Cloud Computing: Cloud platforms store and process vast IoT data for analytics and access.
Embedded Systems: Small computer systems within IoT devices handle data collection, communication, and control.
Data Analytics: Sophisticated tools analyze IoT data for actionable insights.

Applications of IoT
