What is PM2.5?
PM2.5 refers atmosphere diameter less than
or equal to 2.5 micron particles, also referred to as particulate matter into
the lungs. Its diameter is less than 1/20 of the thickness of human hair. PM2.5
composition of the Earth's atmosphere and content of a few components, but its
air quality and visibility has important implications, PM2.5 particle size is
small, rich in a large number of toxic and hazardous substances stay in the
atmosphere a long time, transport distance, and thus a greater impact on human
health and the quality of atmospheric environment.
Ministry of Environmental Protection
through the creation of new standards for air quality PM2.5 concentration
limits
According to the news website of the
Ministry of Environmental Protection, the Chinese Ministry of Environmental
Protection Minister Zhou chaired the executive meeting of the Ministry of
Environmental Protection, approved in principle the "Ambient Air Quality
Standard. The newly revised standard adjustment pollutants items and limits,
additional limit of the average concentration of PM2.5 and ozone 8-hour average
concentration limits, tightened concentration limits of PM10, nitrogen dioxide
and other pollutants.
Response to PM2.5, What smart home can do
for your home?
United States National Aeronautics and
Space Administration (NASA) announced in September 2010, a global air quality
maps, designed to display the density of PM2.5 around the world. Haze days
suggest that you do not get out much, in fact, indoor air quality is sometimes
worse than outdoor. Dust floating in the indoor air, tobacco smoke, bacteria,
viruses, especially the release of formaldehyde, benzene, ammonia and other
pollutants in the decoration materials, all the time endanger our health.
Indoor air pollution damage is women and children. The smart home air quality
testing system is the most important function is to ensure that fresh air and
physical health, prevention of the hazards of harmful gases. Compared to
conventional ventilation equipment, it can be a good performance of the fan and
airflow control system, so that the replacement of the new wind completely
under control, this technology have little effect on the indoor temperature.
Without window 24 hours a day continuously polluted indoor air discharged in
time, while the introduction of fresh air.
Smart home air quality testing system uses
sensor technology, ZigBee technology short-range wireless communications
technology, intelligence analysis software analysis of indoor air quality
testing, and open air purifier, give your family a healthy air environment. The
reason can make an accurate analysis of air quality, because the gas mass
sensor of the type installed indoors, for example, formaldehyde sensor, gas
sensor, dust sensor, etc., corresponding to the material of each type of sensor
interested react to the item feedback to the computer; software on your
computer will generate analysis reports, and suggested that we figure and
improve the current air situation. That science, and convenient.
With the smart home concept to the
transformation of goods, in the construction of affordable housing in the
shadows of the smart home. Smart home is not only easy to operate, novelty,
cool, intelligent, scientific give our lives to bring new breakthroughs.
Through the use of smart home experience, we will slowly explore deeper
connotation rich in smart home system.
