Load cell calibration arduino.

So once you have established two data pairs you can interpolate the rest. Using a load cell or weight sensor you can add this capability to your arduino projects. In this example a 10 kg. The hx711 is easily wired to the arduino using any two digital or analog pins.

To do this upload the following code on your arduino board. Wait until the reading message is displayed on the serial monitor and then place a specified weight item on the load cell. 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. To use a load cell first you need to calibrate it.

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. Next we will explore calibration and test the load cell as a weighing scale. Now that you have your load cell amplifier and microcontroller hooked up you can add your code and start calibrating your setup. 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.

Upload this sketch to your arduino board you need two loads of well know weight. We are interfacing 40kg load cell to the arduino using hx711 load cell amplifier module. In this tutorial we will see how to connect calibrate and display the weight on a small oled display and by using a rotary encoder we will be able to change the units from.
