Air Quality Monitoring with SensorMap [PDF]
2008 International Conference on Information Processing in Sensor Networks (ipsn 2008), 2008 The mobile air quality monitoring network (MAQUMON) is presented. The system consists of a number of car-mounted sensor nodes measuring different pollutants in the air. The data points are tagged with location and time utilizing an on-board GPS. Periodically, the measurements are uploaded to a server, processed and then published on the SensorMap ...
