Taring and Calibrating the Scale

The load cell is connected via a HX711 analog-to-digital converter. It converts the weigth to an 24 bit value. Bevor we can use it as an scale, we have to calibrate the sensor values.

First we need the offste. The offset is the value, we measure, wenn the scale is empty. This is also known as taring. Make shure, you know how to enter the command mode.

Currently configuration is done via python. If you haven’t set up the python environment, please read the instructions on Setting up the NeoBee Python Library.

To tare the weight, follow the steps:

  1. Connect the board via USB to your computer.

  2. Boot the board into command mode.

  3. Press and hold the CMB Button

  4. Now the python part
