Connecting with Arduino and Load Cell

HX711 Weighing Sensor Dual-Channel 24 Bit Precision A/D Module Pressure Sensor

Using a Single Load Cell with Arduino

  • Connect RED wire of load cell to E+ of hx711 module.
  • Connect BLACK wire of load cell to E- of hx711 module.
  • Connect WITHE wire of load cell to A- of hx711 module.
  • Connect GREEN wire of load cell to A+ 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.

There are some using tips from our customers:

  • #1 If your trying to connect a strain gauge directly to it, it won't work, it needs to be in a wheatstone bridge config.
  • #2 The chip sleeps after 60 micro seconds so if you plan on using something like a raspberry pi you should use a signal. Signal type of command to disable interrupts. Arduino or ESP32 will be a better / easier choice.
  • #3 It calculates the change in resistance for the wires connecting the wheatstone bridge too, so if you moving anything around the readings will keep changing.
