Step 2: Assemble

  • Install the printed module and sensor


Step 3: Debugging

Download the program to the arduino,

Start the program and put a 100-gram weight on it to see if it's accurate?

Step 4: Modifying Library Files

  • Open the hx711.cpp file
  • Pull to the last "float Hx711::getGram()" position

Modify the parameters in the red circle, adjust them appropriately, and then download and run the program to see if it is accurate.

  • Debug several times until it is accurate
