Development of a Dust Measurement System

T. Ewetumo, A. O. Oke, J. C. Ehiabhili


Dust particle are particulate matter that can become suspended in the atmosphere and deposited. Dust is present in the atmosphere has significant effect climate, health of human, and strong influence on the solar energy during dry season. The dust monitoring device developed consists of sharp dust sensor module that has capacity of measuring particle size about PM2.5 and above, microcontroller (arduino mega 2560), micro secure data (MicroSD) shield card, with intelligent liquid crystal display unit (LCD) and all are link together to form the complete unit. The dust measuring system compare with available dust device has the correlation of 0.999980 and maximum value of 0.541 mg/m3. Also the sensitivity, resolution and error are 5V/0.1 mg/m3, 0.001 mg/m3and ±0.005% respectively, at 67% relative humidity and temperature of 32oC. The total power consumption of the dust monitoring system is 1.06 W.
