2 Sets 50kg Human Scale Load Cell Weighing Sensor Features
-
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
About 2 Sets 50kg Human Scale Load Cell Weighing Sensor
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
