50Kg body load cell weighing sensor internal is a 1000 ohm half-bridge strain gauge, the measuring range is 50kg load cell, half bridge structure, load sensor is the same one found in digital bathroom scales .
The 50kg load cell 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.
HX711 amplifier AD module uses 24 high precision A/D converter chip hx711. It is a specially designed for the high precision electronic scale designwith two analog input channelthe internal integration of 128 times the programmable gain amplifier.
HX711 amplifier AD module input multiplexer selects either Channel A Or B differential input to the low-noise programmable gain amplifier (PGA), input circuit can be configured to provide a bridge type pressure bridge (such as pressureweighing sensor mode)is of high precisionlow cost is an ideal sampling front-end module.

Load cell is an instrument that helps to determine size of a load (either a force or weight) and converts mechanical force into digital output.
It consists of a metal core and a set of electrical resistances that transform when a force is applied to it. But it returns to its original state after force removed.
It have many purposes, use a load cell, need calibrate it can increase or decrease calibration factor units to get correct weight using a microcontroller.

The sensor have 3 ways to use it:
1. Using a Single Load Cell 1x50kg by Adding 2 Resistors
Connect outer wire(white and black) of load cell to E+ and E- outputs of hx711 module.
Connect middle cable(red) of load cell to A+ input of hx711 module. Connect two 1k resistors to A- input of hx711 module. Then the other end of resistor to white and black wires.
Connect GND of hx711 module to board GND, and VCC to board 5V pin.
Connect DT and SCK of hx711 module to any digital IO pins of board.

2. Using Two Load Cells in a Singel Circuit 2x50kg (100kg)
Connect opposite sides of outer wires(white and black) of two load cells.
Connect outer wire pairs to E+ and E- output of hx711 module.
Connect middle wire(red) of load cell to A+ and A- inputs of hx711 module.
Connect GND of hx711 module to board GND, and VCC to board 5V pin.
Connect DT and SCK of hx711 module to any digital IO pins of board.

3. Using 4 Load Cells in a Single circuit 4x50kg (200kg)
Form a loop by linking same color outer wires(white and black) of the four load cells.
Connect middle cable(red) of one of the diagonals to the E+ and E- outputs of the HX711 module.
Connect the other diagonal to the A+ and A- inputs of the HX711 module.
Connect GND and hx711 module to board GND, and VCC to board 5V pin.
Connect DT and SCK of hx711 module to any digital IO pins of board.

Package included:
8 x 50kg half-bridge load cell
2 x HX711 AD weight module
