Message Queuing Telemetry Transport (MQTT)

maker

MQTT is a lightweight, open-source messaging protocol for constrained devices and low-bandwidth, high-latency networks.

expanded

MQTT facilitates the connection between devices and networks by providing a publish/subscribe messaging mechanism that minimizes network bandwidth and device resource requirements. It is used extensively in IoT applications to handle messaging between sensors and servers, providing reliability and efficiency for telemetry data exchange.

examples

A temperature sensor transmitting data to a remote server via MQTT.

Commonly used in smart home systems to monitor and control climate conditions. A sensor publishes temperature data every 30 seconds, consuming around 1 kB of data per message.

Drone fleet management using MQTT for real-time telemetry data exchange.

Used in agricultural monitoring, drones equipped with sensors publish telemetry data regarding soil moisture and crop conditions. Each drone sends data packets of 2 kB at intervals of 10 seconds.
