I made some changes in my design, still using same load cell and same Arduino, but I changed the load cell interface, now is connected with Load Cell nano shield from Circuitar ADS1230 microcontroller, but I’m still getting this bad result. this is NORMAL?
The scale is outside as you see from the temperature graph. Is protected by wind. The load is a fixed 20.000 grams Iron weight. It’s so strange no temperature related. just going up and down, it seems at fixed time interval
