Welcome to Snuffle.org!

Air pollution is very difficult to measure. Apart from the expensive, professional equipment, more and more inexpensive alternatives become available. Because of the many scattered initiatives, information about the usefulness of these low-cost sensors is difficult to find. This wiki intends to bring together all the available information about sensors (i.e. the components sensitive to air pollution) and sensor boxes (i.e. practical devices containing sensors).

Here you will find information on manufacturers, the current state of technology, sensor specs, sensor issues, and evaluation reports. This is a public knowledge base to which everybody can contribute. If you have information which you would like to share, please register yourself and contribute to this wiki!
