The DustDuino is an open-source project aiming to “help individuals with limited resources monitor PM10 and PM2.5 concentrations, indoors or outdoors.” (http://publiclab.org/wiki/dustduino)
A modern web interface is being built to display data collected from DustDuino devices in a user-friendly format. A database back-end will be required to support the web interface.
The prototype interface can be found here. Login is required, anyone with access should know their credentials already but if not, feel free to contact me to get them.
We have graphs!
