Working principle of resistance strain gauge is based on the strain effect produced when a conductor or semiconductor material that is mechanical deformation under the action of external forces, the resistance value of the corresponding changes, a phenomenon known as "strain effect."
The strain gauges attached to the object to be measured so as to be measured strain was bent together, so that the inside of the metal foil as the strain on the bend. Many metal during mechanical bending resistance will change.
2. Product Introduction

Board printed on the back pin definitions
(Bending strain gages can change the output voltage)
Q: how to use this principle?
This is the bending sensor
He said the principle is, in terms of the degree of bending is detected, such as the strain gauges attached to the carrier: iron aluminum plastic sheet and then bending the carrier, it will change the strain gauge detects the curve of the output voltage.
Strain gauges can be attached to any object, to detect bending, bending module and then we convert the voltage.
