1. 1. 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

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

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

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

   Abstract : 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. READ MORE

5. 4. A Network Camera with a Nose

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

   Abstract : 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. READ MORE

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

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Rudolfs Eriks Agrens; [2018]
   Keywords : ;

   Abstract : 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. READ MORE
