iPhone Temperature Sensor

Question

My question is very similar to this one: iPhone Proximity Sensor. There\'s clearly some manner of thermometer within the iPhone that\'s readable by the OS. Has anyone uncovere

Answer 1

I don't know about previous models, but my iPhone4 goes from cool-ish to very warm in a matter of minutes depending on the various radio usages. So unless "good enough" = "within 20 degrees F or so", then probably not good for ambient measurement.

Unless (maybe you meant this) you could also track radio usage and subtract a temperature variable depending on radio usages. phew. complicated. Easier to just query NWS.

Answer 2

command to get all super-secret names which related with temperature in CoreTelephony framework

nm "/Applications/Xcode463.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/6.1 (10B141)/Symbols/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony" | grep empera

Answer 3

All i could find was CTGetTemperature in CoreTelephony of all places.

Answer 4

I doubt this sensor is for ambient temperature - rather I suspect it is for overheating of the circuits. If that is all you want then great, but again, I think it would be useless for ambient temperature.

just my opinion.
