Partlist

Count Description Value
1 PCB all SMD-parts mounted already
1 pin-header 10-pin

Application

Connect the load cell with the sensor-pcb as shown in the diagram. After this step, connect the load cell to your Gscheiduino (or any other Arduino-compatible PCB):

Democode

A simple example program can be found here: 

#include "HX711.h"
 
// HX711.DOUT  - pin #A1
// HX711.PD_SCK - pin #A0
 
HX711 scale(A1, A0);
 
void setup() {
  Serial.begin(38400);
  Serial.println("HX711 Demo");
 
  scale.set_scale(-723960); // this is for scaling, here for 3kg loadcell
  scale.tare(); // zeroing
 
}
 
void loop() {
  Serial.println(scale.get_units(10), 2); // mean value from 10 measurements, 2 digits
  delay(100);
}
