In A3, the temperature sensor is placed inside enclosure, buried between other parts. I noticed that when I place my A3 on some thermally insulating background (wood, plastic), the temperature sensor shows higher readings. On the other hand when I place it – on the back of enclosure – on some good heat conductant (large metal furniture) – the temperature readings go down. Please see attached screenshot for example. During the day monitor was in the very same place. Only the insulation method changed, nothing else. All of this was observed indoors.

My understanding is that the enclosure is storing heat, causing the higher temperature readings. Unless the heat is effectively radiated, it’s skweing results.

I’ve looked through all uradm monitor designs and I can see, that Industrial has different PCB design. Actually it moves temperature sensor far from main part of PCB and probably even outside of enclosure (as far as I can tell from the pictures).

Can someone with Industrial monitor confirm how much temperature reading changes between 2 scenarios described above? (i.e.: being placed on something thermally insulating vs something thermally conducting?)
