Hi everybody, thanks for your great job!
I’m building a prototype scale with arduino mini, HX711, battery, solar power, temp and humidity sensors. but cannot make it work! the weight drifts over night and day, it is not temperature related, it’s humidity related. I double checked.
Now I’m keeping the scale inside, room temperature is stable +/1 one degree. Humidity goes up and down today is 35% and the weight is down 70 grams, over a 20kg class M test weight.
I experienced that outside, at the beginning I thought could be temperature related, but soon I realized that the only thing driving the weight up and down was the Humidity! Is it possible? how can i solve?
Im’ using a single point 100kg load cell Class 3 IP54.
Anyone ? please help
thanks a lot
