Some Hot Ideas
- One thermometer outside gets you the ambient external temperature:
- Seasons and macro trends
- Recreate and compare the daily forecast
- A baseline to anything going on in the building
- One thermometer inside and one outside gets you a lot of engineering information about the building
- What the heating/cooling cycle is and its efficiency
- How effective the insulation is (both at containing and keeping out heat)
-
If you know its just one person in the room, how much body warmth they are generating. This could correlate to some health conditions (cold or fever) or medication side-effects.
- With two thermometers in a single room and a known number of people could model where they are in relation to the thermometers and triangulate.
