# Where can I ask this series of questions about measuring temperature?

I'm currently designing a system to replace my room thermostat. In looking for parts/modules I came across several options for measuring temperature:

• Fairly accurate temperature
• Temperature (fair bit less precise) + barometric pressure
• Temperature (less precise) + relative humidity

Which got me thinking:

1. Is temperature (electronic measurement) an absolute thing? Or is it influenced by relative humidity? Or barometric pressure for that matter?
2. How big an influence is relative humidity on the human sense of temperature? My intuition says it can't be ignored. If I am correct, how should I incorporate this into the algorithm that controls the central heating system? (Just enough to put me on my way, I'll work the details out myself if need be.)
3. How big an influence does relative humidity have on a house's heating curve (relative to the heating system's curve)? Is it negligible, or should I account for it?

Where do I ask these questions?

• #1 is something for both the physics site (the theoretical side) and the electrical engineering site (how these sensors work, and how other factors affect its accuracy), I think. Am I correct?
• #2 calls for someone familiar with biology, who also has an understanding of algorithms (maybe mathematics, or IT?). What site can I find someone like this on?
• #3 is a thermodynamics thing I guess. Is this for the physics site as well?

The answers to these three questions will help me determine what to buy.

• It sounds like your first question is "what makes air in a room comfortable?" If you have lingering physics or engineering questions on how to achieve that, get to those later. Jul 16, 2014 at 0:04
• That actually seems like an apt summary of my questions, thanks! Though I wouldn't have any idea of where to ask that question either.. Jul 16, 2014 at 0:19
• #2 feels like it's really just a weather question. The formulae for heat index & wind chill are meteorological calculations that convert the measured temperature to the perceived temperature. I think meteorology is considered on-topic for Earth Sciences? Jul 6, 2023 at 21:27
