Strain Gauge Load Cell + ADC Pairing

by FlantasticDan on Wed May 27, 2020 3:20 am

Hello,

I'm wondering if this ADC would be a good pairing with the new Load Cells?

Ideally this would allow me to get the load cell's reading into a Raspberry Pi, any insights are welcome, I've never done anything with analog signals before.

Thanks!

The best choice for those is a dedicated load-cell amplifier. The output of the load cells is just a few millivolts, so you need a differential amplifier with very high gain.

We do not currently stock one. But Sparkfun has these:

Perfect, thanks so much! That's really kind of you to point to another shop, I appreciate that!
