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 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 appear to be much lower than the AEGL-2 limit, as do European Directives (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, rather than regular workplace exposure.
