PermaDAQ: A scientific instrument for precision sensing and data recovery in environmental extremes
(2009)2009 International Conference on Information Processing in Sensor Networks (IPSN 2009)The PermaSense project has set the ambitious goal of gathering real-time environmental data for high-mountain permafrost in unattended operation over multiple years. This paper discusses the specialized sensing and data recovery architecture tailored to meet the precision, reliability and durability requirements of scientists utilizing the data for model validation. We present a custom sensor interface board including specialized sensors ...Conference Paper -
