MQTT stands for Message Queuing Telemetry Transport. It's a way for devices to communicate over the internet, perfect for IoT (Internet of Things).
Here's how it works:
A central hub called a broker receives messages from devices (clients) and then sends them to other devices that need the information.
#MQTT is common in home automation (like smart thermostats and security systems) and industrial settings. It's efficient and uses minimal power, making it great for small devices and gadgets.
