This is a half-bridge load sensor, which is widely used in weight scales. When the half-bridge is being stretched, it sends signal via the red signal wire. You can use multiple load sensors simultaneously to increase the capacity range.
Two sensors full-bridge measurements: 50kgx2=100kg Four sensor full-bridge measurements: 50kgx4=200kg Parallel use to add additional capacity
