This hookup guide will show you how to get started with this amplifier using some of the various load cells we carry at sparkfun.
In this tutorial you will learn about the load cell module its applications and its operation.
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 module is a load cell amplifier breakout board for the hx711 ic that allows you to easily read load cells to measure weight.
Breakout boards sensors sensors weight.
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.
Its output is adjustable through potentiometer and power supply is 18 27vdc wide range.
