In this tutorial you will learn about the load cell module its applications and its operation.
Load cell amplifier module.
This module uses 24 high precision a d converter chip hx711.
It amplifies and converts load cell signal into standard dc current 4 20ma and voltage 0 5v 0 10v output.
The changes in electrical resistance provided by the load cell need to be amplified so that they can be read by an arduino.
Hx711 module is a load cell amplifier breakout board for the hx711 ic that allows you to easily read load cells to measure weight.
Description additional information description.
The sparkfun load cell amplifier is a small breakout board for the hx711 ic that allows you to easily read load cells to measure weight.
We are interfacing 40kg load cell to the arduino using hx711 load cell amplifier module.
The hx711 load cell amplifier was designed for use in household scales.
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.
It is a two channel differential voltage amplifier with channel a having gains of 128 or 64 and.
Brt rw st01a load cell amplifier is designed for signal conditioning on signals from weight brake weight bridge weighing sensor or load cell module etc.

That s exactly what the hx711 board does.
The hx711 load cell amplifier is used to get measurable data out from a load cell and strain gauge.
This hookup guide will show you how to get started with this amplifier using some of the various load cells we carry at sparkfun.
By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell and with some calibration you ll be able to get very accurate weight measurements.
This module uses 24 high precision a d converter chip hx711.
It is a specially designed for the high precision electronic scale design with two analog input channel the internal integration of 128 times the.
Its output is adjustable through potentiometer and power supply is 18 27vdc wide range.
It reads the information from the load cell amplifies the signals and then sends it to the arduino for processing.
Then after learning about calibrating the load cell you will create a digital scale that can measure the weight with an accuracy of 0 0001 grams and also a force gauge.
Breakout boards sensors sensors weight.
It is a specially designed for the high precision electronic scale design with two analog input channel the internal integrati.
Common load cells have four wire to connect the hx711 to a.
