5kg Load Cell Weight Sensor For Weighing Scale Projects

The 5kg Load Cell Weight Sensor measures force using a strain gauge (a thin resistive element that changes electrical resistance when bent). When weight presses on the sensor body, the strain gauge inside deforms, and the weight sensor outputs a small analog millivolt signal proportional to the applied force. It has a rated capacity of 5kg and uses a Wheatstone bridge (a four-resistor circuit that detects tiny resistance changes) internally to produce a stable output. The M4 screw hole fits standard platform scale frames directly.

The load cell 5 kg variant pairs with an amplifier module to boost the millivolt signal to a level readable by Arduino or similar boards. One practical limitation — you must calibrate the sensor with a known weight after wiring, because the raw millivolt output varies between individual load cells. StemVolt provides this weight sensor with trusted quality, ensuring reliable performance and easy usability.
