I am interested in building a system that will monitor temperature inside a grain bin. Essentially I would like to place between three and seven temp sensors inside a grain bin and have a sensor line coming out of the bin where I can periodically connect a ipaq to the array to read the tempatures. My biggest issue is finding some resources on how to connect sensors to a pocket pc in this fashion and the best software to create a user interface. Any assistance would be appreciated. Preferably I would like to be able to read all the sensors with one connection, not having to connect to each line separatley.
BTW I know that these types of units do exist but once I have the basics down I want to modify it further to provide for wireless data acquisition and I may want to add other sensors to the array, so purchasing is not the ideal choice and regardless I am interested in understanding and building the array myself.
Thanks
