Hi,

I stay using load cell 50 kg like this: "Célula de Carga 50kg - Sensores para Robótica - RoboCore" ,
and using the code example of library hx711. in all places visited everybody still using this library and obtained values almost precise, but not working for me.

Thanks for any help.

Not an expert here, but from what I understand you cannot just connect a 3 wire Loadcell to the HX711. Typically 2 or more of these loadcells are wired so that they can detect a difference. However, according to Load Cell with 3 wires - Project Guidance - Arduino Forum you can wire in 2 resistors to make up the difference.

Are you also using an amplifier board, like every one else?
