Development of low-cost and user-friendly sustainable portable particulate sensor

Particulate Matter (PM) has various effects on the quality of air, health, and environment. A newly developed on-line PM10 (particulate matter less than 10 μm) measurement using Arduino as the microcontroller which has multi-connections was able to provide real-time measurement. Shinyei dust sensor (PPD42NS) is used to measure the concentration of the particulate matter at ambient air along with temperature and humidity sensor (DHT22). The aims of the study are to build a portable and user-friendly device for the monitoring of PM10 as a low-cost and sustainable particulate sensor. The device was tested for five days to determine the particulate concentration indoor and outdoor at one site in Dungun, Terengganu. The results showed that the average of the particulate concentration at the indoor and outdoor for five days were 329 and 1587 μg/m3 respectively. The custom-made device can be treated as a low-cost measuring device for particulate matter in ambient air which will be further refined and verified.
