MQTT, which stands for Message Queuing Telemetry Transport, is a lightweight and widely used messaging protocol designed for efficient, real-time communication between devices, applications, and services in the Internet of Things (IoT) and other scenarios. MQTT is known for its simplicity, low overhead, and publish-subscribe communication pattern, making it an ideal choice for resource-constrained and low-bandwidth environments. MQTT is commonly used in IoT applications, home automation, telemetry, remote monitoring, and other scenarios where efficient, low-latency, and reliable communication is essential. It has a large and active developer community, resulting in support across a wide range of programming languages and platforms. MQTT brokers, such as Mosquitto and HiveMQ, are readily available to facilitate MQTT communication.
