DOI

This repo accompanies the publication "Low-Cost, Open Source Wireless Sensor Network for Real-Time, Scalable Groundwater Monitoring" and contains all the scripts necessary to build an interactive web dashboard for a groundwater observatory.

As an example, please see the Cosumnes River Groundwater Observatory, a project of UC Water.

Contents

The clean folder contains scripts that are automatically run every day at 04:00:00 UTC. Together these scripts:

  • extract data from Solinst hardware
  • clean and transform the data (i.e. - adjust for reference elevation, baromaetric pressure)
  • generate a report of remaining battery life and recent monitoring well data and email that report to a contact list
  • push a clean version of the database to the cloud
  • save versions of the database every 7 days to the cloud

The dashboard folder contains (among other files), the three files comprising an R Shiny App:

  • global.R
  • server.R
  • ui.R

Together, these files build the web dashboard.

Shiny Server

We use the open source version of Shiny Server to host the app, which can take place on a cloud computing environment of your choice (e.g., AWS, Azure, Google Cloud).

Project specific note to a future maintainer: Log in at https://shiny.lawr.ucdavis.edu/rstudio/, and note that the app files are located at /srv/shiny-server/gw_obs.
