How to Correctly Calibrate a Load Cell Using HX711 Library for Accurate Weight Measurements?
Hello everyone, I am trying to calibrate a load cell to obtain the correct weight. I followed the instructions from the HX711.pio library, which explains to start with no weight and then divide the raw value by the known weight to obtain the scale factor and use the tare method. However, the resulting values always show a ±10 error. How can I obtain the correct parameters to get the actual value from the load cell, or how can I achieve a better value if no weight is present? The result should be 0 when there is no weight.

Try
averaging @wafa_ath. From your question are you averaging multiple readings during each step to account for any noise in the readings? It will help the factor of your calibration to be more accurateI haven't tried averaging multiple readings yet. I'll implement averaging during each step to reduce noise and improve the accuracy of my calibration. Do you have any recommendations on the number of readings to average for the best results?
Okay
