Load Cell Calibration Arduino

Once you have calculated your calibration factor of your load cell set up you can move on to other code such as the simple scale output example code sparkfun hx711 example ino.

Load cell calibration arduino.

To do this upload the following code on your arduino board. The hx711 is easily wired to the arduino using any two digital or analog pins. Arduino forum using arduino project guidance load cell. Using a load cell or weight sensor you can add this capability to your arduino projects.

In this example a 10 kg. The load cell must also be accurately wired to the hx711 to ensure that the appropriate strain gauge leads are used to approximate the weight given by the load cell. Arduino as load cell amplifier by christian liljedahl christian liljedahl dk load cells are linear. Hx711 is a precision 24 bit analogto digital converter adc designed for weigh scales and industrial control applications to interface directly with a bridge sensor.

To use a load cell first you need to calibrate it. In this arduino tutorial of hx711 load cell amplifier interface. Now that you have your load cell amplifier and microcontroller hooked up you can add your code and start calibrating your setup. Grams kg or pounds.

So once you have established two data pairs you can interpolate the rest. Upload this sketch to your arduino board you need two loads of well know weight. Wait until the reading message is displayed on the serial monitor and then place a specified weight item on the load cell.

Next we will explore calibration and test the load cell as a weighing scale. I have two 3 wired load cells white red black and i m using them to create a 100 kg scale using hx711 but the connections and the coding given in all the sites are not giving the expected results instead they are printing random values.
