Attribute:
Within 1000 ohm half bridge strain gauge load cell range 50 kg half bridge structure
When measured the correct force is applied to the outer strain of the E-shaped beam.
(Eg a strain gauge center white beam plastic arm)
And the outer edge to create the opposite shear force
Such as medium stress beam bending the necessary changes can occur under stress
Side beam stress with another force able to have no barrier.
Specifications:
Model Number: Weighing Scale
Weight: 18 g.
Size: 3.4 × 3.4 cm / 1.33 × 1.33 inches
Capacity: 50 kg / 110lb (each)
Structure: Half - bridge
Output sensitivity: 1.0 ± 15% mv / V
Nonlinearity: 0.05% FS
Input resistance: 1000 ± 10ohm
Output Impedance: 1000 ± 10ohm
Insulation resistance: ≧ 2000 M ohm
The sensor uses the following 3 methods:
1 using external sensors full bridge resistors sensor range measurement range: 50 kg higher for external resistors
2 use only 2-bridge sensor measuring range two sensor range: 50kgx2 = 100kg
3 the use of four full-bridge sensors measuring range range of four sensors and: 50kgx4 = 200kg

This example demonstrates basic scale output. See the calibration sketch to get the calibration_factor for your
specific load cell setup.

This example code uses bogdes excellent library:https://github.com/bogde/HX711
bogdes library is released under a GNU GENERAL PUBLIC LICENSE

The HX711 does one thing well: read load cells. The breakout board is compatible with any wheat-stone bridge
based load cell which should allow a user to measure everything from a few grams to tens of tons.
Arduino pin 2 -> HX711 CLK
3 -> DAT
5V -> VCC
GND -> GND

The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine.
