Studies related to PM2.5 and PM1 using AS-LUNG Sensor in Kuala Lumpur, Malaysia

Low-cost sensors are new emerging technologies that has been applied in research related to air pollution. Low-cost sensor for particulate matter was produced by Academia Sinica Taiwan and widely used in Asia due to the research collaboration under Advanced Institute on Health Investigation and Air Sensing for Asian Pollution (AI on Hi-ASAP). Low-cost sensor named AS-LUNG outdoor and portable has been deployed in several studies in Malaysia where AS-LUNG has been used for cooking exposure studies, ambient air studies and indoor air studies. AS-LUNG sensor also managed to record parameters such as PM2.5, PM1, temperature and humidity. AS-LUNG outdoor sensor is usually used for ambient PM measurement while AS-LUNG portable can be used for both indoor and outdoor. The result of studies related low-cost sensor applications especially AS-LUNG sensor definitely shows accurate PM concentration which highest PM concentration was observed during in indoor environment such as dormitory in Kuala Lumpur City Centre.
