Low-Cost Particulate Matter Sensors

Due to the negative effects of Particulate Matter exposure, more and more inexpensive optical aerosol spectrometers and photometers (low-cost PM sensors) are coming to the market, which are often used to monitor air quality. In addition to the low acquisition costs, these commercial PM sensors are characterized by low maintenance effort, which enable very high data availability in continuous operation. However, questions about the quality of the generated data often remain unanswered.
