This hookup guide will show you how to get started with this amplifier using some of the various load cells we carry at sparkfun.
Load cell amplifier hx711 datasheet.
The hx711 load cell amplifier is used to get measurable data out from a load cell and strain gauge.
The preamplifier handles low voltages.
Hx711 is a 24 bit analog to digital converter adc ic.
Description the hx711 load cell amplifier was designed for use in household scales.
The input multiplexer selects either channel a or b differential input to the low noise programmable gain amplifier pga.
It is a two channel differential voltage amplifier with channel a having gains of 128 or 64 and channel b having a fixed gain of 32.
Connect gnd to gnd vcc to 3 3v and the other three miso or so for short cs and clock or sck to free gpio pins.
The hx711 sensor platform allows you to use your hx711 load cell amplifier datasheet sparkfun with esphome hx711 load cell amplifier.
You can use this scale with any of our load cells to weigh all kinds of things.
What you will need.
