I am new and I am glad to be here with you.
I have been working for a while with Raspberry Pi and I have just got version 3.
I need to have a very robust sensing device that i would be happy for any help I can get.
I would be happy to know if you have any idea which sensor I can use for 4ma to 20ma working with RPi?
I am developing in Python and I would be happy to know if there are any expansion boards from Pololu that I can use with the Pi to enable UART and Sensor connection with input of 4ma to 20ma.
i have a need for at least 8 channels to connect.
I am also hopping to do Modbus communication with full dropping and Multi dropping of RS485 devices.
I would be happy to get any assistance on that as well.
thanks in advanced
