Non Technical Summary
THE OPEN-SOURCE PUBLISHED ENVIRONMENTAL SENSING (OPENS) LABORATORY is proposed. OPENS will create Maker lab space at the OSU and a synergistic forum for environmental sensing technology. The project specifically leverages the confluence of four rapidly developing technologies: 3-Dimensional printing; low-cost solid-state-sensors; low-cost, low-power digital controllers; and open-source publishing. OPENS will provide a web-based formal publishing framework wherein global students and scientists can publish novel and evolutionary advancements in environmental sensor systems. This curated and peer-reviewed digital collection will include complete sets of "printable" parts and operating computer code for sensing systems. The physical lab will include all of the machines required to produce these sensing systems. These tools can be addressed in person or virtually, creating a truly global venue for advancement in monitoring earth's environment and agricultural systems.Advancements in sensor technology have yet to be fully deployed for agricultural purposes primarily due to the expense of sensor assemblages and data analytics. This collaborative project will seek to develop and deploy sensors across a broad spectrum of agricultural applications including water and nutrient fate and transport, pathogen and pest detection, yield, abiotic and biotic stresses to commodity crops, specialty crops, small fruits, forage species, and organic production, and to evaluate pesticide and herbicide efficacy and commensurate impacts to the environment.

Goals / Objectives
The OPENS project proposes the development of a Maker Lab specialized in Environmental Sensing and for deployment of Precision Agriculture across working landscapes for all members of the research and educational communities of Oregon State University. Further, it will be also accessible to researcher and students worldwide via a curated open-archived publication process (led by OSU Libraries) to develop evolving collaborative designs. This space will be installed in Gilmore Hall room 102a and the Gilmore Annex BEE Shop and will be led by Professor John Selker.The OPENS project will give professionally supervised access to 3-D printer(s), laser/plasma cutters, computer controlled milling machines (CNC Routers and controllers), and to a wide range of electronic devices (e.g. Arduino, Adafruits, Beagle Bone, Raspberry Pi). It will include traditional hand tools and facilities such as workbench stations, soldering irons, oscilloscopes, Computer Aided Design CAD software, lathe, milling machine, sheet metal shop all currently maintained by the Department of Biological and Ecological Engineering. On-line and on-campus classes, as well as presentations and workshops, will be given to teach skills needed to make effective use of the sophisticated tools. Remote participants will be supported in their 3-D printing and equipment production on a pay-per-piece basis, so long as their designs are open-published in the Environmental Sensing instrumentation catalog.The main objectives of this project are:Advance the field of environmental and agricultural sensing through development of novel adaptation of 3-D printing and solid-state sensors;Develop new sensing systems that can advance precision agriculture and data acquisition to improve food security, food safety, and environmental stewardship;Create the world's first curated system of peer-reviewed, DOI indexed, open-source publication of designs and validation studies of evolving scientific instrumentation;Provide student access to the power of hands-on experimentation and experimental design through access to a wide range of machines;Develop student and faculty's excitement, creativity and innovation by translating their ideas into functional systems;Promote collaborative learning between faculties and students around the world.
Project Methods
Task 1 - Installation, Accessibility and Safety PlanThe first task is setting-up the logistics needed to create the OPENS Lab, including testing and troubleshooting processes of all equipment. Available space at OSU is identified in Gilmore Hall 102A and the Gilmore Annex BEE shop, where there is ample space for the Lab needs. The OPENS Lab will present two distinct rooms with different making technologies and levels of risk involved. Gilmore 102A will house all equipment that is less hazardous to use: such as hand tools, electronics and Arduino devices, computers, and 3-D printers. This first room will be accessible to students and faculties who have attended training and received certification required to operate these machines. This room will be open during office hours as long as a person in charge of the project is present in the building in case of emergency. A second room will contain the cutting machines, which require a higher level of oversight to ensure safe operation. A certified technician or engineer will staff this room when students are present. Students and faculties will go through training to have access to the cutting machine room and will use it exclusively in the presence of a technician. A schedule will be setup with hours of availability of the machines and technicians.Makers will agree to follow a strict safety plan to use the OPENS Lab. They will have to understand and assess the risk involved for themselves and others when they use the OPENS Lab, especially in groups. A Safety Plan regarding the operation of machines will be developed and will typically include a description of the machine and the procedures for using it, as well as general safety precautions, emergency plans and contact information for the people in charge of each machine.Task 2 - Create Trainings and WOrkshops for Future MakersWhile 3-D printing and other Maker Lab tools are now quite user-friendly and easy to operate, an essential aspect of the OPENS Lab is to establish a culture of training, wherein organizing principles of safe work and learning are fundamental aspects of the educational experience. This will include appropriate training regimes for each machine. The OPENS project will create a certification process for users to become authorized to operate the tools. The lab will also establish a cleaning process to maintain safe conditions which will allow users to easily and regularly remove trash and debris. The training plan will include a description of the operation as well as the safety precautions and emergency procedures for each machine. Various levels of certification will give Makers certain ranges of autonomies in the use of machines. The project will also create a student Maker Lab Association where students will take on some of the responsibilities for safe operation of the machines.The OPENS project will also provide workshops given by specialists in technical operation of machines, electronics and programming languages. Introductions to 3-D printing, CAD program software, basic electronics and physical computing will be given at the OPENS Lab. A wide range of applications often with cross-disciplinary aspects may be needed by individual Makers. To help Makers learn what they need to know to navigate different domains and tools, the OPENS project will develop online workshops through a dedicated website with videos and support documents. Specific workshops on environmental sensing technologies will give Makers the basics to develop their own projects in various environmental domains.Task 3 - OPENS NetworkSharing a Lab space offers an excellent means for Makers to progress on projects and get helpful feedback from experts. Environmental sensing covers a wide range of applications and scientific research and requires competencies from cross-disciplinary domains. The OPENS project brings together an interdisciplinary group of OSU departments and institutions to leverage the expertise of various subject domains. The main domains of application and development will concern environmental sensing applications divided in the following subdomains: atmosphere, agriculture, surface hydrology and sub-surface (Figure 3). Each domain will be led by an OSU faculty member who will create a specialized research community. Each community will share projects and interact through the OPENS project. This network is essential to create a dynamic in the development of cross-disciplinary innovative sensors. It is also crucial to attract users and funding that will ensure the sustainability of the OPENS Lab. Partnerships with other universities will be sought as the needs and applications of the OPENS Lab grow.Student associations also will be created. The objective is to give students the opportunity to learn on their own and use group dynamics to progress through their individual and group projects. The OPENS Lab will be updated with current technology, and the ESML project will build partnerships with companies that provide equipment and services (3D printers, Arduino, etc.) Task 4, Test and deploy sensors in open agricultural settingsThe presence of branch experiment stations (BES) in each of the eco-agricultural zones of Oregon will provide faculty and students with a unique opportunity to evaluate sensors for a broad range of crops and agricultural problems. Oregon's BES provide access to virtually every crop grown in Oregon and their facilities, including on campus greenhouses and farming operations, and allow for testing innovator's abilities to determine difference in yield, water and nutrient fate, pests and pathogens, varietal differences, environmental impacts of pesticides and herbicides, grazing management, rangeland restoration, and impacts of weeds and other invasives. One of the problems currently facing precision agriculture is to have focused most technological development on unmanned aerial vehicles (UAV) without a contemporaneous focus on sensor platforms that can inform agricultural decision-making and environmental sensing. The OPENS lab will allow horticulturalists, weed specialists, agronomists, entomologists, viticulturalists, soil scientists, hydrologists, and engineers to develop ideas for sensor development that can address any number of agricultural production problems and improve agricultural economics and environmental sustainability.Task 5, Open-access repository and peer-reviewed publishing platformSuccess of a scientific project requires communication, collaboration and dissemination. The OPENS project will set-up a dedicated interactive website to disseminate information regarding the on-going projects and the new sensor development process. The website will have a strong educational goal, where Makers will find all interactive training tutorials and workshops. It will also allow the different scientific and technical communities to communicate and interact through a specific blog. This interface will create a strong collaborative dynamic in the making process from a global project idea to its realization and publication.Perhaps the most innovative aspect of this project is to create an open access, peer reviewed publication platform of environmental sensor designs and technologies. Scientific communities worldwide will have the opportunity not only to download all technical information of a sensor hosted on the website, but also to interact, share feedback and contribute to improvement of the technology.

Outputs
Target Audience:The OPEnS lab addresses many audiences. In the agricultural space, the lab has its greatest contributions in the direct support of agricultural research. Examples of these efforts include the dendrometer, which is being used currently in grape and blueberry research, and the sap-flow sensor, which is being used in apple orchard research. These tools and others are also being adopted in commercial agriculture. The eGreenhouse project has installed soil moisture-based irrigation controls in a commercial greenhouse, as well as installing the system in the experimental greenhouses of the North Willamette Experiment Station. The eGreenhouse "HyperRail," which allows automated scanning of entire greenhouses with hyperspectral cameras and other sensors, has also been applied to field research in the study of mosaic fungal infections in wheat, as well as white leaf fungus in white pine. The OPEnS lab is run by Dr. Selker, who is best known for his work in hydrological systems (e.g., he is president elect of the American Geophysical Union's 7,000 member Hydrological Sciences Section). Thus, water resource issues are central to the work of the OPEnS lab. A key goal is to engage citizens in understanding water systems. The SmartRock project, which has now produced more than 200 units, puts sophisticated sensor systems, measuring water temperature, depth, turbidity, and salinity, into the hands of citizens, researchers and students of all ages. These extremely-low-cost systems open exciting new opportunities to observe water at tens of thousands of locations. The open-source design can be made anywhere in the world, by anyone with access to "maker space" tools.
