Are the accuracy specs for these sensors realistic? Are they dumping out of spec sensors on ebay? For example Ebay item 141975980328? I have purchased 2 which are both a few degres off on temp and similar error on pressure. Is there a better source for accurate sensors? Thanks /John
Borch sensors are factory calibrated. Parameters are stored within the sensor itself.
My experience is that they are very precise for pressure.
You would not use this sensor if your need is 'exact' temp.
In general any sensor needs calibration to be 'spot on'.. (for a while)

How have you done your measurements and what reference equipment did you use?
Thanks for the replys. I am comparing my readings to my Oregon Scientific digital thermometer, which agrees with my wife's digital meat thermometer. I'm getting pressure from a nearby station that feeds to Weatherunderground. So I guess the next step is to see if the errors are consistent and can be adjusted in the code.
