HX711 Precision 24-bit analog-to-digital converter (ADC) Breakout Board

Overview

HX711 is an electronic scale module, whose working principle is to convert the measured changes in resistance value changes, through the conversion circuit into electrical output. The module communicates with the host computer through TTL 232.

Advantages

Simple structure, easy to use, stable and reliable performance, high sensitivity and measurement speed and so on.

Application

Widely used in aerospace, mechanical, electrical, chemical, construction, medicine and many other fields, used to measure force, pressure, displacement, strain, torque, acceleration.
