Hx711 chip takes voltage signals as an input and provides digital values.
Load cell amplifier hx711 datasheet.
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.
Description the hx711 load cell amplifier was designed for use in household scales.
Sparkfun load cell amplifier hx711 sen 13879.
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.
