Source Code

Temperature Logger

The temperature logger source code was written to run on the Arduino Pro Trinket 3V, a microprocessor board that is Arduino-technology.


The ChronoDot source code used to encode the current time was written to run on ChronoDot, an ultraprecise realtime clock that is Arduino-technology.

Project STEM is a unique, transdisciplinary program involves high school teachers and students from both Foundations of Technology classes and Environmental Science classes in two interrelated meaningful watershed educational experiences (MWEEs). By leveraging the assets developed by the Hood College Center for Coastal and Watershed studies, the GLOBE program, and the NOAA Environmental Science Training Center, Project STEM employs schoolyards as sites to monitor and assess the impacts of thermal pollution on local stream health. Students completing the program will understand the importance of urban environments as "heat islands" and the ways in which these impacts can be mitigated.
