<h4 class=”user-nicename”>@chuckkir</h4>
Thanks Chuck for offering to help with my coding issues. I have two sets of code that I am currently testing with my Low Cost Sensor Station. Simple_logging.ino is working on my mayfly platform which I am using to test the compensation routines to convert the raw data from the AtlasScientific EC sensor and the RTD temperature probe to µS and ºC.
