Introduction to IoT Devices

IoT (Internet of Things) devices are physical objects embedded with sensors, software, and connectivity to exchange data with other devices or systems over the internet. 🌟

IoT Devices

Key Components of IoT Systems

  • Sensors: Collect data from the environment (e.g., temperature, motion)
  • Actuators: Perform actions based on data (e.g., turning on lights, adjusting thermostats)
  • Connectivity: Enables communication via protocols like MQTT, HTTP, or CoAP
  • Cloud/Edge Computing: Processes and stores data for analysis

Communication Protocols

  • MQTT (Lightweight for IoT)
    MQTT Broker
  • HTTP (Standard web protocol)
    HTTP API
  • CoAP (Designed for constrained networks)

Security Best Practices

  • Use encryption (TLS/SSL) for data in transit
  • Implement strong authentication mechanisms
  • Regularly update firmware to patch vulnerabilities
