4pcs 50kg Human Scale Load Cell Weight Sensors+hx711 Ad Module Weighing Sensors 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 gaugeName: 4Pcs 50KG Human Scale Load Cell Weight Sensors + HX711 ModuleModel: 925119Material: Plastic,MetalWays to use it :- 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.- Use two sensors to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg- Use four sensors to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg Package Included4x 50kg Human Scale Load Cell1x HX711 AD weighing module1x 10Pin Needle
