Analog to digital converter and load cells

Hi guys,

I’m working on a pet feeder and I need to drive three 4 wires load cells.

I would like to use a single HX711 for load cells but the HX711 doesn’t work.

How can I connect this board to my load cells (the have not standard colors).

Or alternatively, can I use a specific ADS to drive 3 load cells?

The ADS1115 is afaik not suitable for load cells.

If nothing else works, read the manual aka the datasheet! (of your load cells, in this case)

For a load cell you need an instrumentation amp to boost the tiny signal with good CMRR, then pass to ADC.
The HX711 combines both in one chip.

Chips designed for thermocouples are also instrumentation amps, some have built-in ADC too.

Do you mean your HX711 is faulty, or that you couldn't get it to work and don't know why?
