Ximimark 4Pcs 50Kg Body Load Cell Weighing Sensor Resistance Strain Half-Bridge Human Scale Load Sensor DIY

I have bought these 50-kilogram bathroom scale load cells and they come with the HX711 amplifier module In this video, I'm going to show you how to connect the 50-kilogram load cells to the HX711 amplifier and how to read the weight values from it with an Arduino I am going to show you different possible connection diagrams four cell circuit two cell circuit and a single cell circuit Theoretically, you could use an analog input of your microcontroller to read the weight directly from the load cells but the voltage-change inside the cell is so small that the sensitivity of the analog to digital converter inside Arduino isn't high enough to do that That's why you need to use an amplifier The working principle behind a load cell is that there are four resistors laid out in a diamond pattern It's called a Wheatstone bridge The circuit has two compression and tension resistor pairs When you
