> tiny thermal camera sensor for inspecting leaks in house for the winter
So just a thermometer gun? It costs like $20-30 on amazon and I've never needed one other than in my home / kitchen. Why in the world do you want a phone for this haha.
I do think I've found the perfect car for you: https://tenor.com/view/homer-simpsons-car-gif-8120474
It would be nice to have constant monitoring against a baseline as well, to alert people when a fever might be breaking out.
I think it'd be an easier pitch in the watch though as that's where they are already shoving most of the health sensors (and have wrist temperature monitoring already).
My point here is I'm not saying it can't ever be something anyone would want because of that rather something selling in another device on Amazon has no weight one way or the other on whether it'd be a good thing to add to a phone.
