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

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Ellen Grace Soroka; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  2. 2. Design av en ejektorspädare samt ett system för partikelmassmätning av dieselavgaser

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Jesper Björkstrand; [2007]
    Nyckelord :;

    Sammanfattning : This master thesis was a subtask of a project called EMIR-1. The goal with the thesis was to build a system for particulate mass measurements in one of the engine test cells at KTH. The particulate mass measurements are planned to be measured with a TEOM. The exhaust gases must first be diluted with air before the sample is sent to the TEOM. LÄS MER

  3. 3. Mätning av partikelmassa i avgaser från en dieselmotor

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Rafael Villasmil; [2006]
    Nyckelord :;

    Sammanfattning : This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.
