    The sensor soldered on the breakout board needs to be reconditioned for accurate readings. From the SHT15 datasheet:

    IMPORTANT: After soldering the devices should be stored at >75%RH for at least 12h to allow the polymer to re-hydrate. Otherwise the sensor may read an offset that slowly disappears if exposed to ambient conditions.

    I did this by leaving my SHT15 in a ziploc bag with a cigar humidifier rated at rh 84%. You could also us a baggy with a small cup of damp salt. Before reconditioning the SHT15’s readings were -7% what they should be. Now it’s perfect. This is something I wish Sparkfun would do in house.

No public wish lists :(
