4PCS 50KG Load Cell Weighting Pressure Sensor Half-bridge and 1pcs HX711 Ad Module Load Cell Amplifier Green PCB for Arduino
Description:
This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year's resolutions, and then forget about a month later).
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
