Air Quality Analyzer using Arduino and Nova PM Sensor SDS011 to Measure PM2.5 and PM10

Air pollution is a major issue in many cities and the air quality index is getting worse every day. According to the World Health Organization report, more people are killed prematurely by the effects of hazardous particles presented in the air than from car accidents. According to the Environmental Protection Agency (EPA), indoor air can be 2 to 5 times more toxic than outdoor air. So here we build a device to monitor air quality by measuring PM2.5 and PM10 particles in the air.

We previously used the MQ135 Gas sensor for Air quality monitor and the Sharp GP2Y1014AU0F Sensor for measuring dust density in the air. This time we are using an SDS011 sensor with Arduino Nano to build Air quality Analyser. SDS011 sensor can calculate the concentrations of PM2.5 and PM10 particles in the air. Here the real-time PM2.5 and PM 10 values will be displayed on the OLED display.

Components Required
Arduino Nano
Nova PM Sensor SDS011
0.96’ SPI OLED Display Module
