Any guidance or assistance very welcome. greg, i know that your request is regarding the supply side of things - measuring rainfall. but here are a few projects, vendors, and organizations i know of who are working on the other end - measuring the result of that rainfall. there is a group called 'floodnet' in new york city using lorawan to measure local flooding, using maxbotix ultrasonic sensors and a loranwan network. they are pretty open about how they build their sensors and collect the data. https://github.com/floodnet-nyc/flood-sensor the aprs system has a mechanism for reporting water height, but it is rather anemic. we're hoping to expand that... http://aprs.org/flood-gauges.html http://www.aprs.org/doc/APRS101.PDF in september of this year, neracoos sponsored the first (us east coast dominated) water monitoring conference. that was primarily for tide monitoring, but the usgs and some hardware vendors were present to discuss issues surrounding event-based monitoring. the applications include hurricanes and the rainfall+stormsurge, construction projects, environmental impact studies, aquaculture, coastal policy-making, etc. there are a *lot* of people doing this kind of work, but here is a short list: - noaa - united states national oceanic and atmospheric administration - https://www.noaa.gov/ - neracoos - https://www.neracoos.org/index.html - gmri - gulf of maine research institute - https://www.gmri.org/ - usgs - united states geological services - https://www.usgs.gov/ - hohonu - they make water level sensors - https://www.hohonu.io/ - maxbotix - the go-to for ultrasonic sensors - https://maxbotix.com/ - rak wireless - loranwan hardware when you don't have time to build it yourself - https://www.rakwireless.com/en-us/technology/lorawan - obscape - environment monitoring - https://obscape.com/site/ there are many more vendor sites, as well as companies who specialize in designing, building, and deploying these things. it is not easy to deploy sensor networks that will survive weather, critters, vandalism, etc. a few of us in mid-coast maine are working on community-oriented systems to measure tide and estuary levels. we have been focused on tide and rainfall monitors, located in areas subject to flooding and storm surges. but the intent is to add temperatures, salinity, ph, and perhaps a few other metrics that will help those working in coastal aquaculture. we have been experimenting with commercial offerings including hohonu, divirod, onset, and obscape, and also diy systems using weewx, lorawan, arduino, maxbotix and some radar-based sensors, typically in partnerships with local schools/university, and the local town offices and public works. https://belfasttide.org/ http://ferry.vinalhavenweather.com/ in particular, the vinalhaven tide monitoring project is replacing the human-with-a-stick system that has been in use for years. during extreme high (and low) tide events, people go to their tide station to measure the water level. but that is difficult/annoying when high tide is at 02:00, or in the middle of a massive storm with huge surges. so we're trying to deploy low-cost, loranwan ultrasonics that might not be noaa-quality, but are good enough to track the flooding and surge that will improve forecasts and help first responders and public policy. hope this helps, m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
