Hello everyone
I want to read a single strain gauge data using HX711 module and ESP32
My circuit is like the following picture
and my code is
#include "HX711.h"
// HX711 circuit wiring
const int LOADCELL_DOUT_PIN = 16;
const int LOADCELL_SCK_PIN = 4;
HX711 scale;
void setup() {
Serial.begin(57600);
scale.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN);
}
void loop() {
if (scale.is_ready()) {
long reading = scale.read();
Serial.print("HX711 reading: ");
Serial.println(reading);
} else {
Serial.println("HX711 not found.");
}
delay(1000);
}
Nothing changes when I deform the strain gauge
It just shows 8388607
So what’s the problem
