The analog outputs from these are fed to HX-711 24-bit ADC boards. An Arduino Nano processes the data and displays it on two banks of eight-digit LED modules. [Sergei] also experimented with a 20 ...

an analog to digital converter specialized for high precision weight sensors used in many industrial applications (see the HX711 datasheet). An advantage of using this component is the availability of ...

going through the effort to add in a calibration routine and a field where you can enter in the weight of your empty spool so it can be automatically deducted from the HX711’s reading.
