  5. 5. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Ellen Grace Soroka; [2020]
    Keywords : Physics and Astronomy;

    Abstract : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. READ MORE
