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:
If your trying to connect a strain gauge directly to it, it won't work, it needs to be in a wheatstone bridge config.
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.
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.
Package includes:
6 x HX711 load cell amplifier board.
