What Is MQTT Protocol?
MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for IoT devices. It provides efficient communication on low-bandwidth and resource-constrained devices using the publish/subscribe model.
How Does MQTT Protocol Work?
MQTT operates around a broker (message server). Devices publish messages to specific 'topics' or subscribe to them. For example, a temperature sensor publishes data to the 'factory/motor1/temperature' topic, while a dashboard application subscribes to this topic to receive the data. QoS (Quality of Service) levels ensure message delivery guarantees.
