Last week I bought a Arduino Duemilanove board and a SHT 15 breakout from Sparkfun.
I use the practicalarduino / SHT1x code from Github written by Jonathan Oxor (June 16, 2009).
At my job (I work on a technical laboratory) I placed the SHT15 sensor together with another commercial
temperature / humidity sensor above a hermetic closed saturated sodium chloride solution.
The theoretical value of the humidity of the saturated sodium chloride solution at 20 °C is 75,5%.
I measure with the commercial temperature / humidity sensor above the saturated sodium chloride solution an temperature 21,2°C and 75,0% humidity.
With the SHT15 breakout I measure above the saturated sodium chloride solution an temperature 21,3°C and 47,5% humidity!
Before the measurements I conditioned the SHT15 breakout 20 hour with >75% humidity.
Who can help me?
No public wish lists :(
