The working principle of the resistance strain gauge is based on the strain effect, that is, when the conductor or semiconductor material undergoes mechanical deformation under the action of external force, its resistance value changes accordingly, this phenomenon is called "strain effect".

Attach the strain gauge to the measured object and make it bend along with the strain of the measured object, so that the metal foil inside will bend along with the strain. Many metals change their resistance when they are mechanically bent.

2. Product Introduction

● Voltage: 5V

● Secondary tube reverse protection~(prevent the power supply from being connected reversely)

● Blue LED power indicator on the board

● Analog output

● Bending angle 0-30 degrees

● The greater the bending, the higher the output voltage

● With zero potentiometer

● The initial output voltage can be adjusted by potentiometer

● Output analog voltage 0-3.5V

● Board size: 32 X 17 mm

● Pin output definition is printed on the back of the board

(The output voltage can be changed by bending the strain gauge)

This is a bending sensor. The principle of the scale is the same as that of measuring the bending conversion. When the strain gauge is attached to the carrier, such as iron aluminum plastic sheet, and then the carrier is bent, the bending output voltage of the strain gauge will change when it detects the bending. We can stick the strain gauge on the object to detect the bending, and then we can bend the module to convert the voltage.
