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!
Go to repositoryThis library is compatible with all architectures so you should be able to use it on all the Arduino boards.
