brand new and high quality Features: 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. Fine workmanship and good performance. Easy to use. Long service life. 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. Specification: Material: Plastic & metal & PCB board Dimensions: 3.4x3.4cm/1.34x1.34inch Color: As shown Quantity: 1 Set Note: 1.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package includes: 4 x 50kg Human Scale Load Cell 1 x HX711 AD Module 1 x 10Pin Needle
