You will need this sensor, especially you are in a busy city where air pollution is high, for example, Beijing. This is particularly true in the case of Malaysia where we might have serious haze conditions as a result of our neighboring country's open forest burning. And for measuring air quality includes the necessity to determine the amount of dust or particulate matter (PM) in the air. Dust is not so bad but really small particles, 2.5µm and 10µm in diameter, can penetrate the lungs causing all sorts of health problems.
PM2.5 Electronic brick is one of the modules in the OCTOPUS series to test the PM2.5 concentration. Based on ZH03 laser dust sensors, it can test the dust particle in the air with high consistency and stability. The PWM output and serial port design also make it easy to operate.
