Loren: No temperature on iPad? That is truly strange… The only thing I can offer there is to wait for the new build that’s in the approval process in the app store. It has different build parameters, including being flagged as a native iPad app. Maybe that will change the behavior?
Tom: The temperature is the temperature measured on the ADC die. I think it’s only accurate to +- 1*C, but also bear in mind the ADC is self heating when the meter is on. So I wouldn’t trust it as a good gauge of the outside temperature, it’s more for performing temperature calibration on the fly, something I plan to add to the firmware when there’s time. If you need a good measurement of outside temperature you should use a thermocouple.
