Dear Colleagues, I’m the Director of the Oregon State Openly Published Environmental Sensing Lab. We’re pleased to announce the OPEnS Lab Virtual Research Expo event below. Please review and distribute to your relevant email lists. Dear Colleague, The Openly Published Environmental Sensing (OPEnS) Lab (open-sensing.org <http://open-sensing.org/>) is delighted to invite you and your colleagues to the fourth annual OPEnS Virtual House on May 31, 2022 from 8-10 am PDT (11am - 1 pm EDT, 5-7pm CEST) and 4-6 pm PDT (7-9 pm EDT). Come and go at your convenience. Students will present the latest advancements in environmental sensor designs in a 3D virtual game environment. Please join us to support these great undergraduate teams, and to learn about the OPEnS Lab equipment, capabilities, and current projects. What is the OPEnS lab? The Open-Sensing Lab is focused on developing practical and transformative environmental sensing projects and research. We typically work with a small client group for each sensor system, and extend the results of the global community as open-source code. We seek to synergistically join open-source sensor technology, 3-D printed structures, wireless communication, and on-line data systems to dramatically extend the capacity and accessibility for distributed environmental sensing. From soldering stations to 3D printers to laser cutters, our lab provides the tools necessary for students, professors, and researchers alike to develop tools used locally and worldwide by the ecological science and engineering community. If you can imagine it, we can build it! We’ll be using Mozilla Hubs <https://hubs.mozilla.com/> as our virtual expo space: https://open-sensing.org/VirtualExpo2022 <https://open-sensing.org/VirtualExpo2022>. Link will go Live May 31. Below we list three examples of active projects <https://github.com/OPEnSLab-OSU/OPEnS-Lab-Home/wiki> being developed in the OPEnS Lab, all of which will be presented at the OPEnS House: -WeatherChimes <https://github.com/OPEnSLab-OSU/OPEnS-Lab-Home/wiki/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. - eDNA <https://github.com/OPEnSLab-OSU/OPEnS-Lab-Home/wiki/eDNA-Sampler>: 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 <https://github.com/OPEnSLab-OSU/OPEnS-Lab-Home/wiki/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 <https://github.com/OPEnSLab-OSU/OPEnS-Lab-Home/wiki/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. Sincerely, Dr. Chet Udell Assistant Professor; OPEnS Lab Director Cara Walter Senior Faculty Research Assistant I; CTEMPs and OPEnS Lab Logistics Andrew McGregor Outreach and Engagement Manager; OPEnS Lab Dr. John Selker Distinguished Professor; CTEMPs co-Director, TAHMO co-Director, OPEnS Lab PI
