The experiment is centered around a small and inexpensive pressure sensor module ... search for one good HX710 Arduino library but simply flunked. Through chance I came across the datasheet of HX711 ...

Two different ASIC approaches can be used for signal-conditioning a MEMS piezoresistive silicon pressure sensor. One is based on a digital scheme ... his retirement from Electronic Design Magazine ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
