Greetings. Teachers, students, or just curious folk, I hope that you will enjoy our students progress as the kids of Chattanooga School of the Arts and Sciences and Hixson High become the Wireless Earth Watchdogs, dedicated towards using microcontrollers and wireless systems to monitor the environmental health of the greater Chattanooga area.  We're using the Arduino platform to build remote water and air quality monitoring equipment that can last long-term in the field.  This blog will focus on techniques, design, and refining our work.
