for my beekeeping project I want to measure the hive weight with load cell and HX711.
The Arduino Pro Mini that I use runs @1Mhz so I can go down to 1.8V and use sleep function. The build will run from 2x AA batteries.
The problem is that the HX711 reports wrong values.
I made two different tests: Same power supply, same HX711 chip and load cell. Tho different Arduino Pro Minis.
- The one working @8Mhz by default, measures correct values.
- The other, @1Mhz with burned fuses, measures wrong values.
I am guessing there is no problem with the HX711 or power running around 3V. The HX711 datasheet states that the chip can run down to 2.6V.
So I tend to believe that the problem occurs when I burn the fuses of the Pro Mini to run @1Mhz.
Can anyone confirm that this is the problem and/or propose any solution or workaround?
best regards, George
