Overview:
HX750 is an electronic scale module, its working principle is to be measured is converted into changes in resistance value changes, and then converted into an electrical signal output circuit.
The module TTL232 way communication with the host computer, Advantages: simple structure, easy to use, stable performance, reliable, high sensitivity and measurement speed and so on.
Application :
Many areas of extensive aviation, mechanical, electrical, chemical, construction, medicine, etc., used to measure force, pressure, displacement, strain, torque, acceleration, etc.
