HX711 always read same value
I had the exact same problem upto an hour ago.

I’m using SparkFun’s load cell combinator circuit diagram here...

...and identified +/-/c on each sensor independently of colour (ca 2kohms between + &amp; -, 1 kohm and dropping with strain between c &amp; +). I had been using screw connectors to make changes easy, especially due to the ambiguity caused by non standard wire colours for each sensor. Obviously at least one connection wasn’t good enough with the screw connectors: It didn’t work after rewiring from scratch several times even with completely different hardware. As soon as i soldered all connections within the Wheatstone bridge and into the load cell amp, it worked fine. After months of frustration, I’ve built 2 scales in the last hour!

Jump leads are fine from the loadcell amp to your arduino/rpi
