Load Cell Adc Arduino

Picture 1 shows the connected and powered up project.

Load cell adc arduino.

In this arduino tutorial of hx711 load cell amplifier interface. A 24 bit analog to digital converter called the hx711 converts the small changes in strain from the load cell into 24 bit changes in voltage arduino 0 5v. The grove adc for load cell hx711 is a 24 bit a d converter designed specifically for the load cell it s quite easy to build your arduino weight sensor system with this module. If you open the serial terminal in the arduino ide or visuino and there is no weight on the load cell you will see.

Vdd is the digital supply voltage used to set the logic level. Vcc is the analog voltage to power the load cell. The changes in electrical resistance provided by the load cell need to be amplified so that they can be read by an arduino. You have created your first digital scale with arduino and hx711 adc weight sensor module.

Common load cells have four wire to connect the hx711 to a. That s exactly what the hx711 board does. The video shows the running project and the serial terminal as different weights are placed on the load cell. It reads the information from the load cell amplifies the signals and then sends it to the arduino for processing.

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. Once the load cell is is hooked up to the amplifier you can hook up vdd vcc dat clk and gnd to a microcontroller such as a redboard or arduino board.
