Grove - Temperature Sensor uses a thermistor to measure ambient temperature. The resistance of thermistor changes based on ambient temperature. This resistance value alters the output of a voltage divider which is measured by an analog input pin and converted to a temperature value. The operating range is -40 to 125°C , with an accuracy of 1.5°C .
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

I'm looking for the temperature equation for the v1.1 of this. I get that the B value has changed from the sample but the equation on the SeeedStudio github produces clearly absurd results (raw value comes in at around 520-530 for room temperature).<
Can you please confirm which thermistors are used on board revisions v1.0, v1.1 and v1.2?
I am trying to find accurate B values.
I have purchased this recently and trying to follow example at http://learn.adafruit.com/tmp3...
However I do not find the resolution in millivolt/de
