Senior Project - Canary


An Indoor Air Quality Monitoring System

Senior Project: 1995-1996
Matthew Crosby, Kerry Kruempelstaedter, Bradley Martin and Robin Sam
Golden, CO

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.
