Load Cell Calibration Wait until the Reading message is displayed on the serial monitor and then place a specified weight item on the load cell. Using the A key, you can increase the calibration_factor one unit and you can use the Z key to decrease it to get the correct weight. Now your scale is calibrated!
What is HX711 module?
HX711 module is a Load Cell Amplifier breakout board for the HX711 IC that allows you to easily read load cells to measure weight. It is a specially designed for the high precision electronic scale design, with two analog input channel, the internal integration of 128 times the programmable gain amplifier.
What is a load cell in Arduino?
A load cell or a Strain Gauge is basically a Transducer which generates an electrical signal whose magnitude is proportional to the force applied. The various load cell types include Pneumatic, Hydraulic, and strain gauge. Hx711 and Load cell Interfacing with Arduino, Circuit Diagram: Arduino HX711 and Load cell
What is the calibration range for the load cell?
The calibration, for this application, will achieve a measuring range from zero to 5kg and Zero will be the load cell resting point with no load on the calibration platform. Images are provided as a quick reference to the calibration procedure.
What is a load cell in Electrical Engineering?
A load cell or a Strain Gauge is basically a Transducer which generates an electrical signal whose magnitude is proportional to the force applied. The various load cell types include Pneumatic, Hydraulic, and strain gauge. Before you Start the Programming, first of all, make sure you download the necessary library.
What is the use of Arduino Uno USB cable for calibration?
While Arduino UNO USB cable is used in this project, once the calibration is complete, the USB cable could be replace with a wireless module such as Bluetooth to catch data untethered. The Arduino sketch, which I called the firmware earlier, has two modes of operation. One mode for calibration and one mode for sending data to another application.
