Define out-of-the-box configuration for Nitrogen Dioxide 10m/30m/60m/4hr/8hr limits that matches the sensor capabilities.

To define out-of-the-box configuration for Nitrogen Dioxide 10m/30m/60m/4hr/8hr limits that matches the sensor capabilities.

An incompatibility needs to be resolved - the [AEGL-2 limits for NO2](https://www.epa.gov/aegl/nitrogen-dioxide-aegl-program) requested by Prometeo are beyond the CJMCU-4541/MICS-4514 NO2 sensor’s range (max 10ppm).

@mrodrise - could you confirm with Joan which limits should be used instead please? It may help to note that [the NIOSH, OSHA and ACGIH limits](https://www.cdc.gov/niosh/pel88/10102-44.html#:~:text=The%20current%20ACGIH%20recommendation%20is,as%20a%2015%2Dminute%20STEL.) appear to be much lower than [the AEGL-2 limit](https://www.epa.gov/aegl/nitrogen-dioxide-aegl-program), as do [European Directives](https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=CELEX:32017L0164) (at least for NO2). Those limits are within the sensitivity range of the Prometeo NO2 sensor. The discrepancy may be because the AEGLs are intended for [rare exposure](https://www.epa.gov/aegl), rather than regular workplace exposure.
