Programming Instructions
Install HX711 library via Arduino IDE:
Basic setup:
- Define DOUT and SCK pins
- Initialize scale with begin()
- Perform tare for zero reading
- Calibrate with known weight
Calibration process:
- Remove all weight for zero
- Place known weight on scale
- Adjust factor until reading matches
Simple Control - Library handles ADC reading
Memory Function Calibration saves on poweroff
Used in professional systems
Reliable and repeatable
√ Library examples available
√ Supports multiple load cells
Troubleshooting
No readings:
- Check wiring connections
- Verify power supply
- Avoid loose connections
Inconsistent readings:
- Perform calibration
- Check mechanical mounting
- Avoid external vibrations
