Definition
The Message Queuing Telemetry Transport ( MQTT ) protocol and its secure counterpart MQTTS are lightweight and efficient communication protocols designed to exchange information between different devices on a network
Imagine you have sensors, machines, or IoT (Internet of Things) devices that need to share data. MQTT allows these devices to send and receive messages quickly and easily.
How does it work?
MQTT works a bit like a messaging service. There's a central server, called a broker , that acts as a message distributor. Devices can be publishers or subscribers .
- A publisher sends messages to the server (broker) (example: a sensor sends its temperature).
- A subscriber ( subscriber) receives these messages (example: a computer or a smartphone which monitors the evolution of the temperature).
- The server (broker) ensures that each subscriber receives the right information at the right time.
Main applications of MQTT and MQTTS protocols
MQTT is used when data needs to be exchanged regularly and reliably, even if the network connection is unstable or of poor quality. It is particularly suitable in the following situations:
Remote Device Monitoring
For example, environmental sensors that measure temperature, humidity or air quality.
Industrial automation
To monitor the status of machines in a factory and adjust their operation in real time.
Home automation
To connect lighting, security or temperature management systems in a smart home or building.
Transport and logistics
Real-time tracking of vehicles or goods.
