The working principle of resistance strain gauge is made based on strain effect, namely the conductor or semiconductor materials in mechanical deformation under the action of external force, the resistance value of the corresponding change, this phenomenon is called "strain effect".
Will be the determination of strain gauge on the content, make its bending together as by to determine strain, so the inside of the metal foil as the bending strain. A lot of metal in the machinery with the change of the resistance to bending.

2.Product introduction
Voltage: 5 v
Diode reverse protection ~ (to prevent power supply meet the)
On a board with a blue LED power light
Analog output
The higher the bending, the greater the output voltage
With zero potentiometer
Can use potentiometer to adjust output starting voltage
0-3.5 V output analog voltage
The board size: 32 X 17 mm
The board back output pin definition
(bending strain gauge Can change output voltage)
 
Q: how does this use, principle?
This is bend sensor
Detecting principle is also, bending degree of conversion, the strain gauge on the carrier, such as: iron and aluminum plastic sheet Then bend the carrier, bending strain gauge detected output voltage will change.
Can stick strain gauge on any objects, bending test, and then we bending module switching voltage.
