Just out on Early View at Methods in Ecology and Evolution, a paper led by James Mickley outlining the design of an affordable envionmental microcontroller unit (EMU) that can measure and log several envioronmental variables. What’s more, the units can be constructed from easily sourced DIY electronics components that collectively cost about $20. James and the team has produced an extensive supplement detailing how to make the units and code to run them, which is available from the accompanying GitHub repository. Great work James!
