I have four strain gauges (50kg) with 5 wires each (red, black, white, green, yellow) and want too measure weight of a platform. I assume those should be hooked to hx711 load cell amplifier and esp32 MCU if possible.
I see two problems there:
- Strain gauge has recommended excitation voltage 10-15V which is not compatible to hx711 or esp32
- I assume I need to hook them to Wheatstone bridge, but single strain gauge is already a Wheatstone bridge. Can't figure out what should be the wiring scheme.
