This time we use 50 or 100Kg laod cells. We need 4, one for each corner that we will put over a solid plate. So make the scheamtic below and then upload the code. This will give you the weight taht is palced on top of the solid plate.
This Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration, you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.
