Hi, just to be clear. When you set the min temp of 160 it can’t see anything below 160 in measurement mode.
When I run your code in low-temp mode I get a black image… which is expected.
When I turn on high temp mode I get a lot of noise pixels:
I can also make out an outline of myself.

Default settings are -10C to 140C. So, you need to turn on high temp mode to access -10C to 450C.
I’m not sure why pixels are appearing white in the image. It should be all black. There’s a bug here that will need to be debugged. The high-temp mode option was user-contributed. This was not supported initial by me. It appears it only works in AGC mode. I’ll have to debug why it doesn’t work in linear measurement mode.
