Wiring & usage notes

Check the pin labels on the Weight Sensor Amplifier HX711 and match them to your controller voltage, ground, and signal pins. Keep wiring short and verify the logic level before powering the module. Load cells need a proper amplifier such as an HX711 and solid mechanical mounting. Small twists or uneven force can change the reading.
