Having just completed my first HM4 build and having read so many different posts, I have a few thoughts concerning the thermistor.
Everyone mentions the difference in temp inside the case. Since that is normal because the Raspberry Pi is a computer and does generate heat, why not do one of two things. The first option would be to drill a hole in the case and put the thermistor in the hole sticking out a little bit and using a dab of silicon on the inside or the hole keep the thermistor in place and to help insulate it from the heat inside the case. The second option would be to get a plug like the probe plugs and solder the thermistor to the plug and then screw the cap back on. When this plug is plugged in it will give you the ambient temperature that is not effected by the hot air inside the case. The only downside to this approach is the plug will be small and can get lost easily. One solution for this is to either paint the cap a bright color or to use a label machine and make a flag type label indicating ambient temp probe. One of my label makers uses a tape that is bright yellow. Much harder to loose.
Just my two cents. What do you think? Good idea or bad?
If this idea has already been brought up by some else they have my apology. Did a search about this but could not find any mention of these ideas. Thanks
