 Good afternoon everyone So I like to talk about building capacity through the development of low-cost 3d printer what printed weather stations So this project is supported by USAID and the National Willow Service to build capacity to reduce risk whether whether related risk in developing countries through observing and communicating weather and climate information to rural communities So as most you know developing countries are some of the most data sparse regions in the world as shown on the map on the right One of the reasons commercial sensors are expensive and difficult to maintain in these areas So our idea is to come up with a low-cost solution to help with this problem So this low-cost solution is use 3d printer technology and micro sensors Which are relatively cheap these days to basically print and replace Instruments as they fail and allow met services to build their own instruments So here's a here's a couple images of our first prototype of our weather station or housing sensors and platform This is all run on a single board raspberry pi computer and the total cost is on the order of two to three hundred dollars So it's not very expensive So what are the components? So we've designed a built a wind speed sensor wind direction Precipitation gauge and then the housing components for the raspberry pi and other parts of the station We also have a radiation shield and in there we have the micro sensors for measuring Pressure temperature and humidity and the last step that we're currently working on is integrating solar power and Wireless communication so we can put these in remote areas around the world So how do you make a 3d printer weather station? Well first you need a you need a 3d printer High-quality plastic filament in some kind of computer aid drawing software CAD software to design design your Instruments so here's some of our our designs that we've developed So here's the design for the precipitation rain gauge wind speed sensor wind direction the radiation shield and then here's a finished product of the rain gauge funnel which In a pinch can be used for other applications So we've done some initial comparisons if you're wondering so this is temperature in relative midi Time series. I think our measurements are doing pretty well except for there is some solar solar heating issues That's required us to redesign the radiation shield. So this is research and development Good results from our pressure sensor. We're pretty happy there But we still have some work to do on our wind speed sensor as you can see there So it's not all all perfect and we're also evaluating our other other sensors at the moment So our initial project is focused in Zambia part of the reason that there's already an ongoing early warning project there And the idea is to extend our observation network and also develop and build new societal applications for that region So we've partnered with the Zambia Met Service. We've done our initial Our initial evaluation site survey last month Our first deployment is planned for February of this coming year With a more extensive network plan for about August of next next year And then start focusing on integration of these data into applications in year two and the plan is Have this project over a five-year period and hopefully we're going to expand to other days first regions such as the Caribbean Pacific Islands and other regions in Africa So talking to the the Zambia Met Service We've we want to focus on some set of applications early on Improving their flash flood early warning systems water resource management, especially for hydroelectric power We visited with local farmers for agriculture first for large-scale farming to substance farming and also there's there's a Fish fish farms there for ponds and also for health applications such as looking for malaria regions from malaria outbreaks So so I also think there's educational opportunities with this activity So such as integrating this into an university course say in atmospheric sciences to help them help students learn how to use the Instrumentation monitor, but also this could be an interdisciplinary course where you can bring in Engineering students computer science students to improve on our design Integrate help with the programming display of the data and so on so it could be a really a really great course I think and into the future And there's other opportunities I can think of one is you know science activities and primary and secondary schools They can help build and design their own instruments whether enthusiasts who want their instruments in their backyard and the great thing is that this is going to be an open research in the future So people can download and build their own instruments So with that I just want to mention this project was inspired by Kelly Spanberg Who's who's done a lot of work in this area over the years and unfortunately he passed away this past August So he'll be missed so thank you very much
