The load cell amplifier board for the HX711 IC allows you to easily read cell load to measure weight. By connecting an amplifier to your microphone you will be able to read the resistance changes of the load cell and with some calibration, you'll be able to get very accurate weight measurements. This can be useful for creating your own industrial scale, control process, or simply the presence of an object
