Community Observation Networks for Air (CONA)
NIWA's CONA research projects explore the potential of new technologies, including low-cost sensors, internet of things and visualisation and social media to address community air quality.
Monitoring outdoor air with ODIN networks
ODINs (Outdoor Dust Information Node) are devices designed and built at NIWA that are designed to be deployed in grids of 25 to 100 units across a town. Each unit measures particulate matter levels (PM10 and PM2.5) every 10 minutes or faster, sending data to the cloud via the mobile phone network.
These data can be converted into maps of air quality which are readily animated.
ODIN grids have previously been deployed in the following locations. For those with hyperlinks, you can view animations of data collected by the ODINs.
- Arrowtown (2020 and 2019)
- Masterton (2020)
- Invercargill (2020)
- Christchurch (2019)
- Motueka (2019)
- Alexandra (2018)
- Gisborne (2018)
- Rangiora (2016-17)
Monitoring air inside the home
Since 2012 NIWA has been experimenting with low-cost sensors for use in the home.
From 2012 to 2017 NIWA developed PACMAN – a device to observe and explain sources of polluted air in the home. You can read more about this work here.
Since 2019 we have been experimenting with “HauHau” sensors (HauHau Ltd, Auckland iaqsensors.com), exploring differences in indoor pollution sources and infiltration of outdoor sources between hundreds of NZ homes.
