1. Introduction
The PM 2.5 Air Quality Monitor is designed with a laser particulate matter
sensor for and a high-precision humidity/temperature sensor.
PM2.5 is:
A lot of pollutants existing in the air, where the dust-like particles floating in the
air are called particulate matter (PM). Distinguishing particle size, the particles
smaller than or equal to 2.5 microns, i.e. PM2.5 is commonly known as
particulate matter in units of μg/m3. With the diameter less than 1/28 of human
hair thickness, the particles are so fine as to penetrate the alveoli, enter the
blood vessels directly, and even circulate throughout the body via the blood.
Therefore, the impact on the human body and ecology cannot be ignored.
The regulations for PM2.5 in Taiwan:
The Air Quality Act of Taiwan Environmental Protection Administration
stipulates that the average value shall not exceed 35μg/m3within 24 hours.
The standard adopted by Taiwan is the same as the standard of theUS,please
refer to the US AQI if to view the AQI in Taiwan.

Lookup Table for AQI and PM2.5 Value
AQI is :
The acronym of Air Quality Index, a new indicator for the ambient air quality,
and used to describe the status of air quality.
