So I just transferred my project from a bread board (where everything was working great) to a more permanent solution and I'm having a weird issue where my LM34 sensor starts creeping up from about 65F (correct) to over 100F even though the ambient temperature hasn't changed. Anyways, unless I'm mistaken, it seems really sensitive to sunlight- as the temps start dropping as soon as I put it in the shade, but doesn't seems to stabilize around 70F.
I could imagine a slight increase in temp due to morning sunlight during a cool morning, but 40F bump? I'm not placing it in an enclosure- not sure why it seems to be self heating. Ideas?
