HX711 Load Cell Amplifier Module

HX711 module is a Load Cell
Amplifier breakout board for the HX711 IC that allows you to easily read
load cells to measure weight. 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 programmable gain amplifier. The input
circuit can be configured to provide a bridge type pressure bridge (such
as pressure, weighing sensor mode), is of high precision, low cost is
an ideal sampling front-end module. 

HX711
is an IC that allows you to easily integrate load cell into your
project. No need of any amplifiers or dual power supply just use this
board and you can easily interface it to any micro-controller to measure
weight. 

The HX711
uses a two wire interface (Clock and Data) for communication. Compared
with other chips, HX711 has added advantages such as high integration,
fast response, immunity, and other features improving the total
performance and reliability. Finally it’s one among the best choices for
electronic enthusiasts. The chip lowers the cost of the electronic
scale,at the same time,improving performance and reliability.
