The difference between M-Bus and Modbus
At first glance, M-Bus and Modbus are very similar, no matter on alphabet or pronunciation. The more similar things are usually easier to get confused. At the same time, these two terms are related to the electricity meter industry, so let's learn the difference between M-Bus and Modbus today.
What is the difference between M-Bus and MODBUS communication ?
M-Bus Communication: M-Bus is a communication protocol used between meters and the central data collection system or Pre-Payment unit. Widely used on new projects where the building infrastructure can be designed accordingly.M-Bus is available on a wide variety of gas, heat, electricity, and cold/hot water meters.
Lorawan Energy Meter & Antennas
Lorawan energy meters are also known as:Lorawan electricity meter, lorawan power meter, Lorawan smart energy meter etc. LoRaWAN is a Media Access Control (MAC) layer protocol built on top of LoRa modulation. so we can say we build our Lorawan energy meter based on LoRa technology.
LoRa and LoRaWAN technology principle and advantages and disadvantages
LoRa and LoRaWAN are currently very popular wireless communication technologies in the field of Internet of Things, LoRa is a physical layer technology, LoRaWAN is a communication protocol. They adopt low-power wideband wireless modulation technology, which can provide long distance communication service in long distance, low speed and low power.
