What is MQTT and how is it used in IoT?
MQTT stands for Message Queuing Telemetry Transport. It's a lightweight messaging protocol ideal for IoT devices.
Why is MQTT preferred for IoT over other protocols?
MQTT is preferred because it's efficient, uses minimal bandwidth, and supports low-power devices, making it perfect for IoT.
Can you give me an example of how MQTT works in a smart home?
Sure! In a smart home, a thermostat can publish temperature data to an MQTT broker, and other devices can subscribe to that data to adjust settings accordingly.
What are the security measures for using MQTT?
MQTT can use SSL/TLS for encryption, and authentication methods like username/password or client certificates to secure communications.
