Cement bridge strain gauge bending module
Power supply DC: 5V
Output accuracy 0.001V
The output voltage is -4 to +4V. This depends on the forward and reverse bending.
The module is composed of a full-bridge integrated high-precision strain gauge
Bend reading at 3-5 degrees can reach full-scale output
Magnification 2500 times
The output zero position is also adjustable.
Size: 50.5X30.5 (unit mm)
Weight: 7.8 (in grams)

Module description, a simple sentence is that the output voltage is different

with different curvatures.
Can be used to detect wood bending, bow bending, bridge bending, called bending

The working principle of the resistance strain gauge is made based on the strain effect,

that is, when the conductor or semiconductor material is mechanically deformed under

the action of external force, its resistance value changes accordingly. This phenomenon

is called the "strain effect".
Attach the strain gauge to the object to be measured and bend it with the strain of the object to be measured, so that the metal foil inside bends with the strain. Many metals change their

electrical resistance when they are mechanically bent.


Question: How to use this and how?
This is a bending sensor
The principle of the scale is also to detect the bending degree. The strain gauge is

attached to the carrier such as: iron, aluminum, plastic sheet, and then the carrier

is bent. When the strain gauge detects the bending output voltage, the output

voltage will change.
You can attach a strain gauge to an object to detect bending, and then our

module bends to convert the voltage.

Many people ask how to calculate the output and the corresponding value?
Strain gauges are not pressure, they are bending deformation.
Actual value divided by voltage, such as 1KG weight output 1V, which is

1V divided by 1000 = 0.001V per gram
The output of the posted object is different, even the scale is calculated in this way.
