- Probably not what you are looking for, but you left out:
-
- 4). Dew point measurment?
- Some temperature sensors, one solid state cooling device,
- an optical sensor, and some control circuitry...
- Wouldn't this be "self calibrating" (or only depend
- on the temperature sensor's accuracy)?
- I haven't tried this, just thought about it,
- (probably read about it somewhere...)
