Human Scale Load Cell Weight Weighting Sensor 50KG Half-bridge Strain Gauge Bathroom Scale

Description：
This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales.

The sensor is a group of half-bridge strain gauge, there are 3 ways to use it :
1. Use one sensor with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements.
2.Use two sensors to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg
3.Use four sensors to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg
