How can you develop for hardware connected to an iPhone OS device via the 30pin connector?

Question

I have a small thermometer with a mini-usb connection. I would like to connect it via USB adapters to the 30pin connector on my iPhone. I am a paid dev ($99 version) and can't find much info on the hardware stuff. Is it possible to access this hardware with my current setup? I just want to access the data being generated via the temperature sensor.

Thank-you for any help!!

You won't be able to access that device from an iPhone, but you definitely can make a custom thermometer. I made one using an Arduino (circuit board controller).
