The Openly Published Environmental Sensing (OPEnS) Lab (open-sensing.org) is delighted to invite you and your colleagues to the fourth annual OPEnS House on March 21, 2023 from 4-6:30 PM PDT at the Precision Agricultural Systems Center (3531 SW Campus Way, Corvallis, OR). Come and go at your convenience. Food will be provided. Students will present the latest advancements in environmental sensor designs.
Please RSVP, as we need to know how many people will join us that day: https://forms.gle/urC1w73tG2e2xp8f9
There will be a Zoom session from 4:30-5 pm PDT. Please contact Cara Walter (email@example.com) for the link.
We look forward to seeing you join us to support these great undergraduate teams and to learn about the OPEnS Lab equipment, capabilities, and current projects.
Below we list examples of active projects being developed in the OPEnS Lab, all of which will be presented at the OPEnS House:
WeatherChimes: a system to measure unseen phenomena (soil water content, electrical conductivity, and temperature; air temperature and humidity; light intensity) and transform them into real time aesthetically engaging sensory experiences like music, sound and projections. Just published in HardwareX.
eDNA: A 24-bottle, affordable, open-sourced, remotely deployable, fully automated, and customizable system for extraction and preservation of DNA traces from water bodies.
Smart Rock: a submersible sensor suite that monitors pressure, temperature, turbidity, and salinity (EC) of a small stream over time and is designed to be built by anyone with or without extensive experience in electronics.
Dendrometer: The ultra-low-cost Dendrometer created at the OPEnS Lab is being developed to measure the radial trunk fluctuations, a proxy for water stress, for a grapevine with a diameter between 25 and 50 mm at 0.5 micron accuracy with virtually zero hysteresis. The OPEnS Dendrometer alleviates typical failure points and inaccuracies by using a frame of zero-thermal expansion carbon fiber, and spring tension and a linear magnetic encoder to enable and track movement of the frame.
