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.
