## Description

MQTT, short for Message Queuing Telemetry Transport, is a lightweight messaging protocol, ideal for situations where small code size and unreliable or bandwidth-constrained networks matter. It uses a publish-subscribe model, which makes it particularly suitable for machine-to-machine communication in networks with remote locations or devices with limited resources, such as in the Internet of Things (IoT).
