my code are working but the value not change only its come 0.000 only why

#include "HX711.h"
HX711 W;
void setup() {
  Serial.begin(9600);
  W.begin(35, 32);
  

}

void loop() {
  Serial.println();
  Serial.print(W.get_units(), 3);

}

my load cell is rsl803, its 750kg variant

Hello satpor3
Keep it simple and stupid.
Run some tutorials to the hardware selected.
If you are happy with the results of the tutorials you can merge these to the project by using control structures.
Have a nice day and enjoy coding in C++.

Get a Sparkfun HX711. Power the analog part (VCC) with 5v and the digital part (VDD) with 3.3v.

i have only this one , not avilable in sparkfun procucts, is it possible to get result using this module

Maybe. Power the HX711 with 5v. Use a voltage divider or other means to reduce the DT 5v high down to 3.3v, so you don't fry your ESP32. Check the datasheets to see if the ESP32 high on SCK is high enough for the HX711 (check the tolerance on the ESP high output); if it is, should work. If not, pull it up as needed.

Also, be sure E- is grounded. It isn't on some green boards.
