An Indoor Air Quality Monitoring System
Senior Project: 1995-1996
Matthew Crosby, Kerry Kruempelstaedter, Bradley Martin and Robin Sam
IEC develops systems to control and monitor building environments. With the
need to conserve energy in the building environment, buildings have attempted
to seal off leakage to the outside. This has caused indoor air to re-circulate
to the point that the quality of the air has become an issue. The EPA is
developing indoor air quality (IAQ) requirements that facilities will have to
meet. Being involved in the building controls business, IEC has seen an
opportunity to add this important feature to their existing system. This
project involved the development of sensor code to collect, linearize, limit
check, send fault alarms, buffer, and time synchronize data, a communications
library and modem interface to allow communication of the data to a remote
site, and a graphical user interface to manage the system. The software was
developed in C and Visual Basic.
