The world’s largest independent environmental sensing network is the Smart Citizen network, according to Fast Company. At the heart of the network is a small kit with a host of environmental sensors.
These include elements for tracking carbon dioxide, nitrogen dioxide, temperature, humidity, light and sound. When assembled, the module sits outside a window or balcony to record local conditions.
Researchers from Barcelona developed the platform and associated website to give people more proactive roles in monitoring atmospheric conditions. Their devices have been deployed by citizen scientists around the world.
