We would never have gotten this far without the generous help of many friends, wise acquaintances, and other hackers. Sensebridge was created as part of a community, and we want to keep that spirit.

At Sensebridge we believe in keeping things open source. All versions of North Paw electronics are essentially Arduino clones with some extra stuff onboard, you can program them using the Arduino IDE.
