This is a demonstration of a load cell based "Kitchen Scale" using a Bluetooth Low Energy link to an Android application running on a tablet. This application is based on the Avia HX711 Load cell amplifier IC using a modified library with median filtering (included - https://github.com/CalPlug/Espressif_ESP32-Scale/tree/master/libraries/Hx711EXT). The application was developed using the Arduuio IDE. The connected Android applicaion provides display of weight, tare, and 2-point calibration functions. All ESP32 and Android code is available in this reposititory.
