A community run network of air pollution monitors

Community Environmental Monitoring is a Sydney based project to create a community owned and run network of air pollution monitors (PM 2.5 & PM 10) in response to the increasing pressures on ecosystems and our health coming from ill-considered development and the current climate crisis in particular.

We are building and deploying particulate pollution monitors using instructions from the wonderful OK Lab Stuttgart project, Luftdaten, from Germany. We use their monitor designs, and link to their maps and open data. There are also many other grassroots environmental monitoring projects around the world that we learn from.

The particulate sensor used in the Luftdaten model is the low cost SDS011 sensor, which has been shown to be a valuable tool for indicative particulate matter PM 10 and PM2.5 monitoring by comparison testing within Australia and overseas. These low cost sensors provide the possibility for a large community-based sensor network, to give us a more fine-grained picture of pollution exposure.

This project is coordinated on the sacred lands of the Gadigal people of the Eora Nation that have never been ceded. The causes of the pollution we monitor today are inextricably linked to the dispossession of First Nations peoples, and the ongoing disregard for peoples' and ecosystems' health by colonial and subsequent institutions. We support First Nations peoples' statements that their sovereignty and ongoing connection to land and culture is 'critical to life on this land'.

Add a monitor to the network

Sign up to request a monitor for your home, organisation, school, workplace etc. . We can install a monitor anywhere that has a power outlet and wifi. We're interested at expanding our capabilities to support more locations with solar or other technologies.

Access all the data

The monitors in the network take regular readings of PM 2.5 and PM 10. Through our connection with the Luftdaten network, you can get access to the full dataset, updates, and information about the monitors' locations.
