Strain gauges to weigh the weight of things

Hello,
I’m new on the forum and a new Arduino User.
I have the task to weigh weight with a strain gauge, see photo. But I have no idea how to write the code because I do not know how to address this strain gauge. From a research assistant, I just got a package with the strain gauge product number, but no information on usage, code, and what’s needed to create a function that replaces a scale. Can someone please support me from the forum?
Many Thanks

Google term to use is "FSR" (force sensitive resistor).
Start here.
Leo..

That's indeed an FSR.

It's basically a resistor that changes value under pressure - so it's also not a strain gauge, instead it's a kind of pressure sensor.

All you need to read it is a pull-up resistor.
