Hi,
I want to read the soil moisture data from CS650 by using Arduino Mega 2560 board. CS650 output format is SDI-12 as well as Serial RS232.
Can i connect CS650's Green(Tx)/Orange(Rx) wires directly with Mega's RX0/TX0 or shall i use the Max3232 module between arduino and CS650?
if someone has tried this earlier, please share the wiring diagram/example source code.
Thanks.
