I am trying interact with a loadcell that is 3 wired. I am using arduino uno or nodemcu adafruit huzzah and sparkfund hx711 module.But i cant take scales. I only getting 0.0 grams and when i applied force to my loadcell nothing change.
I have 2 pcs loadcells one of them has green black and red cables other has white black and red. I measured resistance between wires for each loadsensor. Loadcell1(has green ) Green and Black difference 2Kohm. So they are E+,E-. I have 5x220 ohm series (1.1K) and series E+ and E- to Input-(A-) after all connect red cable to input +(A+). I cant reach proper scale values. I am only getting 0.0. Do you have any soluiton about that?
