What is MQTT?
The abbreviation MQTT comes from the words MQ Telemetry Transport. It specifies a simple data transmission protocol, which is currently considered the easiest and most frequently used method of data transfer to the cloud. Data published using the MQTT protocol is in text form, which means that you can convert the data structure to JSON (or any other text format) and then publish it without major problems. The MQTT protocol is dedicated to transmission for devices that do not require high bandwidth. By limiting the transmission speed, the protocol provides greater reliability.
