now is few years when I am using my beeScale (Arduino Uno + Load Cell + HX711) and in ideal weather (15+ degrees celsius and humidity below 70%) are readings almost perfect (10-50g per 100kg is ok for me).
But when weater is not so kind, below 15 degrees celsiur or is humidity over 70% then magic begins.
On a rainy day we would expect from -0.1 kg to -1 kg but instead of this we got reading from -5 kg to + 5kg depends on what probby only God knows.
So now i have question.. is there any way to calibrate or protect that scale (or loadcell or hx711) to minimize that error?
Temperature, and humidity effects everything,much or less much.
What is the resolution in the data from the load cell? I don't know that load cell. Does it produce an analog signal or does it AD convert its sensor and transmits digitally?
What does the specs say about accurazy during various temperature span etc.?
Is the beehive just sitting on the load cells or are they glued in place?
Wood shrinks and expands with humidity. If everything is glued rigidly then the load cells may be experiencing lateral forces which could mess up the measurements.
Hive has 1-2 cm of space around so it can not touch anything. Now i have scale at home.. (outside) with no load on it and in cold weather still strange readings... ill have to try something figure out..
hm.. maybe it can be problem also my box for electronics (where brain of scale is in) cuz it's wooden...and mybe accumulate even more humidity? could it be?
