MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for IoT (Internet of Things) devices and low-bandwidth, high-latency or unreliable networks. It works on top of TCP/IP and enables efficient, bi-directional communication between devices, such as sensors, actuators, and other IoT endpoints, and applications. MQTT uses a publish-subscribe model where messages are published to a broker, which then distributes them to all subscribers who have subscribed to the relevant topic.
MQTT has several applications in various industries, including:
– Smart home automation: MQTT can be used to control and monitor smart home devices, such as lighting systems, thermostats, and security cameras.
– Industrial IoT: MQTT is widely used in industrial settings to monitor and control manufacturing processes, optimize resource usage, and improve supply chain management.
– Healthcare: MQTT can be used to monitor patient health data and transmit it securely to healthcare providers, enabling remote patient monitoring and telemedicine applications.
– Agriculture: MQTT can be used to monitor agricultural infrastructure, such as soil moisture, temperature, and humidity, and automate irrigation and fertilization processes.
– Automotive: MQTT is used in connected car applications to enable real-time vehicle diagnostics and firmware updates, and to facilitate communication between the vehicle and other IoT endpoints, such as traffic management systems.
