IoT (Internet of Things) protocols are essential for enabling communication between devices. Here's a breakdown of common protocols and their use cases:

1. MQTT 📡

  • Description: A lightweight publish-subscribe protocol ideal for low-bandwidth, high-latency networks.
  • Use Cases: Smart home systems, industrial automation, and mobile apps.
  • MQTT

2. CoAP 🌐

  • Description: A web transfer protocol optimized for constrained devices and lossy networks.
  • Use Cases: Machine-to-machine (M2M) communication, sensor networks.
  • CoAP
  • Explore CoAP vs MQTT

3. HTTP/HTTPS 🖥️

  • Description: Standard protocols for web-based data exchange, widely used for IoT APIs.
  • Use Cases: Cloud-connected devices, web interfaces for monitoring.
  • HTTP
