Hi,
I'm looking for a digital temperature sensor which has a single wire interface I can use directly to my modulation input of my RF transmitter. I hope to avoid using a processor. I can trade off most things like resolution/accuracy, although I would like to measure 150degrees C.
I've looked at a few (eg http://www.ti.com/product/tmp141 and http://www.maxim-ic.com/datasheet/index.mvp/id/2794) but these look like they need some configuration input from a master.
Any idea if this kind of stand alone, single wire digital output thermometer exists?
Thanks
