Hi all,
My name is Putri Syarah from Indonesia,
I want to ask about the hx711 amplifier module,
Can someone explain the working process of hx711 from analog input to output to digital ? I don't really understand the working process of the hx711 sirkuit circuit.

I use a 5 kg load cell sensor and a nodemcu esp8266 microcontroller
I attached hx711 circuit and module :

Thank you,
Putri.
 

To make a weight scale, 4 load cells must be connected in a wheatstone bridge and the wires must be connected to the HX711 module according to the markings. If you see the block diagram of the HX711 module, you can see that, the input from the wheatstone bridge is fed to a MUX. The MUX output is fed to a Programmable gain amplifier. The amplifier Output is then fed to a 24-channel ADC. The ADC's output is fed to a digital interface. And finally, we get digital output from the module. If you use "HX711.h" library in Arduino IDE, you will get your result direct in pounds.
