Air quality is measured by the below metrics

Indoor Air Quality (IAQ) - Wikipedia Article

Relative Humidity (RH %) - Wikipedia Article

Volatile Organic Compounds (VOC ppb) - Wikipedia Article

Carbon Dioxide (CO2 ppm) - Wikipedia Article

For ease of understanding the iZone summarise the overall IAQ from the worst reading of the VOC and CO2 sensors. The categories and levels are as follows:

Each of the states and territories of Australia is responsible for monitoring air quality and publishing data in accordance with the national NEPM standards

Each state and territory publishes air quality data for individual monitoring locations, and most states and territories publish air quality indexes for each monitoring location

Across Australia, a consistent approach is taken with air quality indexes, using a simple linear scale where 100 represents the maximum concentration standard for each pollutant, as set by the NEPM

These maximum concentration standards are:

The air quality index (AQI) for an individual location is simply the highest of the air quality index values for each pollutant being monitored at that location

 AQI bands, with health advice for each:

Air Quality button: Go to the "Monitoring" tab and press the Air Quality button to access the air quality monitoring

Overall Indoor Air Quality: Based on all the parameters being measured this is a guide to the overall indoor air quality

Indoor VOC's being measured: This is the level of VOC's being measured at the the Nexus+ screen. Press the button "Good" to see the actual reading in parts per billion and a guide of VOC levels

Indoor CO2 being measured: This is the level of equivalent CO2 being measured at the the Nexus+ screen . Press the button "Great" to see the actual reading in parts per million and a guide of CO2 levels

Indoor Relative Humidity being measured: This is the level of RH being measured at the the Nexus+ screen in percentage. Press the button "Normal" to see the actual reading in % and a guide of RH levels

Outdoor Air Quality index: This is the outdoor AQI being measured at air quality station closest to your home. Press the button "Good" to see the actual reading and for a guide of AQI levels

Current outdoor relative humidity: The current outdoor relative humidity from the last reading received

Current outdoor temperature: The current outdoor dry bulb temperature from the last reading received
