Introduction to the Internet of Things (IoT)

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.
