Detailed explanation-1: -MQTT is the standard protocol for messaging and data exchange for the Internet of Things. The protocol uses a publish/subscribe architecture. The technology provides a scalable and cost-effective way to connect devices over the Internet.
Detailed explanation-2: -MQTT has a client/server model, where every sensor is a client and connects to a server, known as a broker, over TCP. MQTT is message oriented. Every message is a discrete chunk of data, opaque to the broker.
Detailed explanation-3: -MQTT is a standards-based messaging protocol, or set of rules, used for machine-to-machine communication. Smart sensors, wearables, and other Internet of Things (IoT) devices typically have to transmit and receive data over a resource-constrained network with limited bandwidth.
Detailed explanation-4: -MQTT is a communication protocol based on a publish and subscribe system. Devices can subscribe to a topic or publish data on a topic. Devices receive messages that are published on topics they are subscribed to. MQTT is simple to use and it is great for Internet of Things and Home Automation projects.
