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

3. 2. Evaluation of a heated inlet to reduce humidity induced error in low-cost particulate matter sensors

   Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

   Författare :Piotr Czernicki; Mathias Kallmert; [2019]
   Nyckelord :particulate matter; optical particle counter; relative humidity; low-cost; pm sensor; heated inlet; Technology and Engineering;

   Sammanfattning : The number of low-cost particulate matter (PM) sensors available on the market has increased in recent years. They are affordable, compact and require no maintenance which means they easily can be deployed and utilized for real-time air monitoring. However, the accuracy of low-cost PM sensors has been reported to vary depending on several factors. LÄS MER

4. 3. Bluetooth Low Energy Industrial Sensor

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Sammanfattning : Industrial Internet of Things (IIoT) market is rapidly growing and expected to further expand in the incoming years. To keep up with such a fast pace, new wireless technologies need to be developed to accommodate the huge number of devices expected to connect to the internet. LÄS MER

5. 4. A Network Camera with a Nose

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Rasmus Björklund; Eric Kuan; [2018]
   Nyckelord :Low-cost sensors Air sensors Air quality monitoring; Technology and Engineering;

   Sammanfattning : Some network cameras have already several other sensors besides the image sensor to extend the capabilities of the camera. It is then only natural to think what can be achieved when air sensors are added into the mix. In this master thesis the applications of air sensors coupled together with network cameras have been investigated. LÄS MER

7. 5. Sensor Network for Real-TimeAir Quality Measurement

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Rudolfs Eriks Agrens; [2018]
   Nyckelord :;

   Sammanfattning : In this research, a sensor network for air quality measurement is developed. There is a need for air quality assessment in rapidly developing urban areas. Prolonged real-time monitoring can provide a direct feedback on how increasing traffic and construction work affect air quality. LÄS MER
