Library for interfacing meter SDM120 with Arduino, tested whith Mega 2560
A direct approach to the meter is used without the need to know the Modbus protocol, an approach paradoxically more robust than some Modbus libraries I tried before writing this!

This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
