Sauna steam meter/löylymittari

löylymittari.txt

This document is to establish prior art on a method and apparatus to measure estimates of subjective sauna steam (löyly) effects in real time or from a recorded log.

There's no intent to patent or otherwise restrict the use of this invention. The purpose is to allow free use and further development of the idea, invention and/or apparatus to anybody for any purpose.

Subjective effects of sauna steam (löyly) are quantified by a transformation of instantaneous temperature, moisture and optionally air pressure with a mathematical or computational formulation. These can be based on for example existing "heat indices" commonly used to quantify the feel of the weather. In implementations these have been recorded with commercial temperature, moisture and pressure sensors
 The measurements are combined with a computer program for quantifications of the subjective effects. This estimate can be presented in various formats. Numerical display and light color modulation have been implemented
 Furthermore, the progression of the steam have been measured in multiple points and these have been visualized with color and brightness modulation of a "light strip". The discrete measurement points can be interpolated or predicted over space and/or time with various methods
 Latencies in the measurements can be compensated with algorithmic methods that make use of regularities in dynamics of the sauna steam.
