Small monitoring stations open up internet access as air pollution becomes clearer

Free public Wi-Fi is often looked at with suspicion since it either requires dealing with slow speed or an exchange for personal information. But free and secure Wi-Fi is now available as long as people are willing to help improve the air quality of the area, thanks to TreeWiFi.

Developed by designer Joris Lam, these monitoring birdhouses provide several different services: it collects data on the local air that is uploaded to a central server, it indicates air quality to the public using LED lights, and when the air is clean, opens up the local server for free Wi-Fi. This way, people are not only given up-to-date information on the state of their air but also directly benefit from it. Raising awareness for the issue of air pollution is not the only pro of this model—it is also more cost efficient than most monitoring stations.
