I want to read mVolt

Hi everyone,
I want to impruve a new project. İts name bascul. I want masure kg and ı have real enduatrıal loadcell and those loadcells genarate minivolt and ı want use they with arduino. How to use loadcell with arduino and how to read mv with arduino and is it necessary calibration? Thanks

You will have to use a A/D converter that matches your voltage range.
The builtin ADC in the Arduino's have a minimum range of 0 to 1.1V. If 1.1mV is enough resolution and your measured voltage is always between 0V and 1.1V, they you could use the built in ADC.
If not, you will have to use some external ADC chip. I use ADS1118, they have a +-256mV range and 16bit resolution. Roughly 7.8uV per bit.

Thank you
