With the advent of the Raspberry Pi and other extremely cheap and power SBC computers with low power requirements, I'm migrating away from PIC's. So I'm wondering, does anyone recommend any USB environmental sensors? I'm working on a HAB project and was looking for temperature, pressure, basically any sensor for any variable at high altitudes :) Figure I'll tie them all together via a hub and a Raspberry PI unit once it comes out. -Josh --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
