Making sense of sensing

No comments

Stine had a meeting Friday at COWI (a Danish Engineering Consultancy Company) about sensing air pollution. Some problems with our current project proposal arose. 

O3, temperature and NO2 are important factors in air pollution. 

It is a bit unclear whether the sensor we have ordered (MQ-135) is actually able to detect NO2. The data-sheet is not very specific, only refering the to general category of nitrogen oxides, NOx. 

Another project, AIR (http://www.pm-air.net/) very similar to ours used sensors from citytech, so possibly we have to change the type of sensor we are going to use.

COWI suggested to contact FORCE and DMU
