Airава сыйфатын мониторинглау станциясе белән катнашыгыз

GAIA һава сыйфаты мониторы реаль вакытта PM2.5 һәм PM10 кисәкчәләренең пычрануын үлчәү өчен лазер кисәкчәләре сенсорларын куллана, бу һаваны иң зарарлы пычратучы матдәләрнең берсе.

Аны урнаштыру бик җиңел: моның өчен WIFI керү ноктасы һәм USB ярашлы электр тәэминаты гына кирәк. Бәйләнгәч, сезнең реаль вакыт һаваның пычрануы дәрәҗәсе безнең карталарда шунда ук бар.

Станция 10 метрлы су үткәрми торган электр кабельләре, электр белән тәэмин итү, монтажлау җайланмалары һәм өстәмә кояш панели белән берләшә.

Air Quality Index (AQI) Calculation

The Air Quality Index is based on measurement of particulate matter (PM_2.5 and PM₁₀), Ozone (O₃), Nitrogen Dioxide (NO₂), Sulfur Dioxide (SO₂) and Carbon Monoxide (CO) emissions. Most of the stations on the map are monitoring both PM_2.5 and PM₁₀ data, but there are few exceptions where only PM₁₀ is available.

All measurements are based on hourly readings: For instance, an AQI reported at 8AM means that the measurement was done from 7AM to 8AM.

Air Quality Scale

The AQI scale used for indexing the real-time pollution in the above map is based on the latest US EPA standard, using the Instant Cast reporting formula.

IQA	Health Implications	Cautionary Statement
0 - 50	Good	Air quality is considered satisfactory, and air pollution poses little or no risk	None
50 - 100	Moderate	Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.	Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
100 - 150	Unhealthy for sensitive groups	Members of sensitive groups may experience health effects. The general public is not likely to be affected.	Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
150 - 200	Unhealthy	Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects	Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
200 - 300	Very Unhealthy	Health warnings of emergency conditions. The entire population is more likely to be affected.	Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
300 - 500	Hazardous	Health alert: everyone may experience more serious health effects	Everyone should avoid all outdoor exertion
