This module uses 24 high precision A/D converter chip hx711, specially designed for the high precision electronic scale
The load sensor is a group of half-bridge strain gauge, there are 3 ways to use it.
Use one load sensor 50kg 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 weight sensor 50kg to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg
Use four weight scale 50kg to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg
