As part of building management standards related to conditions such as sick building syndrome, the miniature IAQ Profile monitors are designed to provide a visual representation of a building's indoor air quality. Because a large number of units can be networked, the system can display precise changes in the concentration of selected IAQ parameters over time at different locations. The Micro IAQ Profile Monitor uses the sophisticated and reliable ZigBee wireless mesh system. Mesh network systems are cost effective, easy to install, and simple to use: the nodes that make up the mesh network are automatically configured with good signal routing.
