Out of curiosity, I bought a strain gauge sensor module after it appeared on sale. This write-up is fuzzy, since I decided to write based on a quick inspection of it. Have fun reading my little post ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...

Strain gauges are those tiny sensors that look like little wire resistors, which is essentially what they are. These transducers are sensing devices that measure load, pressure, torque, displacement, ...
