This seems awfully silly to me. At least it\'s cheap, about 13 cents.
Maybe it\'s useful for something else.

A comparator with a reference current output.

I was hoping for something completely different.
We use NTC thermisters.
What I would really like is to be able to point some kind of (cheap)
IR sensor at a general area of power components and get a rough
estimate. Instead of tacking thermisters to transformers and FETs
which is kind of a pain.
I looked into those IR sensors used in cheap $20 temperature guns but
the lens assembly, I think, makes that not too easy or cheap to
implement.

I use a MLX90640 with a Raspberry Pi 4 as IR camera
https://makersportal.com/blog/2020/6/8/high-resolution-thermal-camera-with-raspberry-pi-and-mlx90640
it was more expensive, about 60 USD, but works OK.
Could be same module?

Yes, that and the alliexpress thing would work.
But they cost too much for this conumer grade inverter/charger
application
Thank you for those ideas !

Could you provide a link for that? I cannot find anything below EUR 40.
