Creep effect removal. Load cell storage over long time #236

Open dev-techshlok opened 2 years ago

dev-techshlok commented 2 years ago

Hello, I am designing a load cell monitored storage. Where I can keep something for months to monitor the weight just like beehive monitor projects. I am facing the creep effect after reading the common error document. I have checked any wire r other issues everything is in place. Even I have used a 30Kg loadcell setup from a market product already. Just added HX711 with 4 wires.

My result is increasing over time by around 2 grams per 12-15 minutes.

Is there a way to compensate for this error in code?

Also is there any formula to compensate temprature

sorry, i can't help you with that.

Dear @dev-techshlok, dear community,

on this topic, I would like to point out the More on load cell temperature compensation discussion on the Hiveeyes forum, where @hsors shared his story of improving stability by researching into temperature compensation. Just recently, he added a corresponding implementation. Big kudos and thanks a stack, Henri!

With kind regards, Andreas.
