Interpretation of terms:

modbus: is a serial communication protocol. One node is a master node, and the other nodes participating in communication by using the Modbus protocol are slave nodes. Each slave device has a unique address. In serial and MB + networks, only the node designated as the master node may initiate a command (on ethernet, any device can send a Modbus command, but typically only one master node device initiates a command).

LoRa: the abbreviation from "Long Range" is an ultra-Long-Range wireless transmission scheme based on spread spectrum technology. It belongs to one of the internet of things technology.

RS 485: a typical serial communication standard specifies the electrical characteristics of the bus interface, i.e. the definition of 2 logic states: the positive level is between +2V to +6V, which represents a logic state; a negative level between-2V and-6V represents another logic state; the digital signals adopt a differential transmission mode, so that the interference of noise signals can be effectively reduced.

MQTT: a message protocol based on a publish/subscribe paradigm. It works on the TCP/IP suite, a publish/subscribe messaging protocol designed for remote devices with poor hardware performance and in case of poor network conditions, for which it requires a message middleware.
