Sensing the Air Quality

PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope. Particles come in a wide range of sizes. Particles less than or ...

Evaluation of LowCost Sensors for Ambient Monitoring

Lowcost sensors are an opportunity to improve the spatial and temporal resolution of particulate matter data. However, such sensors should be calibrated under conditions close to the final ones before any monitoring actions. The paper presents the results of a collocated comparison of four models of lowcost optical sensors with a TEOM 1400a analyser.
