Abstract
Air pollution due to Particulate Matter (PM) is an increasing concern of global extent. It has been the focus of many research projects worldwide and the latest low-cost technology is offering an ease and cheap way to monitor PM concentration. In this research, a low-cost PM monitoring platform was built with the objectives of evaluating its feasibility and its performance in mobile measurements, as well as characterizing the concentration profiles of PM along the measurement route. The rack railway in Stuttgart was utilized as means of transportation for this low-cost monitoring system with which the temporal and spatial distribution of the PM10, PM2.5 and PM1 concentration along the route was attained. The measurements were conducted for around two months from mid of January until mid of March 2019, during the operation hours of the rack railway. The results showed that the PM concentrations were dominated by fine particulate matter (PM2.5 and PM1) along the route of the rack railway. Higher PM concentrations were measured near the federal highway and high traffic area as compared to the residential area. An overestimation of PM concentration using low-cost sensor platform was observed during high relative humidity conditions as compared to the professional aerosol spectrometers.

Summary
Air pollution is a serious health concern. It is one of the major environmental challenges across the globe. Mobile measurements help to measure the air quality in an extended area and provide a high spatial resolution of the measured parameters. These measurements enhance the information obtained from a network of stationary monitoring stations, which are often influenced by near emission sources, at least when situated in urban hotspot areas, and represent mostly the local surrounding conditions [10]. In order to measure the temporal and spatial distribution of PM in the ambient air, a low-cost PM monitoring platform was built. This platform contained a low-cost PM sensor, sensors to measure temperature, relative humidity and pressure with respective electronic parts. A GPS was included to determine the geographical position
