The brain of the project is as always the arduino, you can use any Arduino board model. Through this project, you will be learning how to make a small weighing scale. This circuit is designed for getting reading at serial terminal if you need to add display refer LCD interface with Arduino. We use a load cell of 10kg, a module that amplifies the output of load cell and an Arduino. The parts I am using includes an Arduino Uno, straight bar (100g) load cell sensor and an I2C 16x2 Arduino LCD display from DFRobot. Using a Single Load Cell. Verify Your Load Cell Wires. The output signal produced by the load cell is in range of millivolts, so we need an amplifier to convert the signal into a level that we can later transform it into a digital signal and process it. So HX711 module amplifies the low electric output of Load cells and then this amplified & digitally converted signal is fed into the Arduino to derive the weight. Note: VCC is the analog voltage to power the load cell. This assembly can be used with Arduino UNO, Mega R3 or similar boards. Arduino Load Cell Handbrake. Working with a Load Cell and an Arduino. The output can be monitored on the Serial monitor of Arduino IDE. 34 Replies. A number of times, the glass has cracked. I am using an Arduino Uno and HX711 amplifier to collect data from a load cell.
