Hello,

It is possible to develop software for arduino to communicate with this current sensor for sens the Main AC or other ?
The communication is RS485 Modbus.
The communication protocol download : http://www.support-carlogavazzi.se/downloads/Controls/Protokoll EM24 V1R0 ENG 040906 .pdf

I make a lot of sensors but not very good to create a new software ...

Thanks all.
