A strain gauge is a device used to measure strain on an object. This strain gauge module uses the strain gauge BF350-3AA to detect the strain, with the amplifier and potentiometer on the board to adjust the measured results, users can easily get the result with any microcontroller such as Arduino-compatible board. This module can be positively used in measuring deformation (for example, across a bridge by loading positions and effects) in engineering and in physical distortions proportional to loading or thermal environments. In everyday, this module can be used to applications such as gating a traffic light into a new sequence when a car on a lightly traveled side-street enters a Tee-intersection. For better using on our crowduino, we add a crowtail port so that you can plug and use directly.
