Description:

This Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration, you'll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control, or simple presence detection. The HX711 uses a two-wire interface (Clock and Data) for communication. Any microcontroller's GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711. Load cells use a four-wire wheat-stone bridge to connect to the HX711. These are commonly coloured Red, Black, White, and Green. Each colour corresponds to the conventional colour coding of load cells:

  • Red (Excitation+ or VCC)
  • Black (Excitation- or GND)
  • White (Amplifier+, Signal+, or Output+)
  • Green (A-, S-, or O-)

Please keep in mind that some load cells might have slight variations in colour-coding.
