Also you ll see how to use the load cell module with arduino.
Load cell amplifier module.
This module uses 24 high precision a d converter chip hx711.
Load cell amplifier module hx711 quantity.
Breakout boards sensors sensors 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.
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.
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.
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.
Hx711 module is a load cell amplifier breakout board for the hx711 ic that allows you to easily read load cells to measure weight.
In this tutorial you will learn about the load cell module its applications and its operation.
It is a two channel differential voltage amplifier with channel a having gains of 128 or 64 and.
The changes in electrical resistance provided by the load cell need to be amplified so that they can be read by an arduino.
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.
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.
It reads the information from the load cell amplifies the signals and then sends it to the arduino for processing.
