/* * https://circuits4you.com * https://circuits4you.com/2016/11/25/hx711-arduino-load-cell/ * 2016 November 25 * Load Cell HX711 Module Interface with Arduino to measure weight in Kgs Arduino pin 2 -> HX711 CLK 3 -> DOUT 5V -> VCC GND -> GND Most any pin on the Arduino Uno will be compatible with DOUT/CLK. The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine. */ #include "HX711.h" //You must have this library in your arduino library folder #define DOUT 3 #define CLK 2 HX711 scale(DOUT, CLK); //Change this calibration factor as per your load cell once it is found you many need to vary it in thousands float calibration_factor = -96650; //-106600 worked for my 40Kg max scale setup //============================================================================================= // SETUP //============================================================================================= void setup() { Serial.begin(9600); Serial.println("Press T to tare"); scale.set_scale(-96650); //Calibration Factor obtained from first sketch scale.tare(); //Reset the scale to 0 } //============================================================================================= // LOOP //============================================================================================= void loop() { Serial.print("Weight: "); Serial.print(scale.get_units(), 3); //Up to 3 decimal points Serial.println(" kg"); //Change this to kg and re-adjust the calibration factor if you follow lbs if(Serial.available()) { char temp = Serial.read(); if(temp == 't' || temp == 'T') scale.tare(); //Reset the scale to zero } } //=============================================================================================
