Air
The Ambient Air Monitoring page allows you to view the air quality in different areas of your living space or monitored environment in real time. This page is designed to provide a clear and intuitive overview of various environmental parameters, making it easier to make decisions to maintain healthy and safe air.
To keep the dashboard simple, we have integrated detailed calculations of the ACI and AQI indices (see dedicated section). These indices are calculated for each zone, and you have the possibility to activate or deactivate the zones directly from the dashboard. You can also show or hide our comments. Alerts are automatically generated when the thresholds are exceeded.
AQI
The Air Quality Index (AQI) is a composite measure that evaluates air quality by taking into account several air pollutants. Here's how the AQI is calculated in your configuration:
Pollutants Taken into Account:
Suspended Particles: PM1, PM2.5, PM4, PM10.
Pollutant Gases: NO₂, SO₂, O₃, CO, CO₂.
Calculation Methodology:
Data collection: For each type of pollutant, standardized data is collected via the corresponding sensors.
Maximum value selection: The AQI is determined by the maximum value among all monitored pollutants, reflecting the level of pollution of greatest concern.
Rounding: The final AQI value is rounded to the nearest whole number to simplify interpretation.
AQI Standardization:
Objective: To facilitate visualization and comparison by reducing the AQI to a scale of 0 to 500.
Normalization Scale:
0-50 AQI (Good): 0-100%
51-100 AQI (Moderate): 101-200%
101-150 AQI (Unhealthy for Sensitive Groups): 201-300%
151-200 AQI (Unsanitary): 301-400%
201-300 AQI (Very Unsanitary to Dangerous): 401-500%
Above 300 AQI: Capped at 500%
Alert Thresholds:
Thresholds are set to indicate different levels of air quality, allowing for rapid response if safe levels are exceeded.
ACI
The Air Climate Index (ACI) is a composite measure that integrates several environmental parameters to assess overall air climate conditions. Here are the details of its calculation:
Parameters Taken into Account:
Standardized Air Quality Index (Standardized AQI): 40%
Normalized temperature: 20%
Standard Humidity: 20%
Standardized Carbon Dioxide (Standardized COâ‚‚): 10%
Standardized Volatile Organic Compounds (Standardized VOC): 10%
Calculation Methodology:
Data retrieval: Normalized values of each parameter are extracted via the corresponding sensors.
Applying weights: Each parameter is multiplied by its respective weight.
Weighted Sum: The results are added together to obtain the overall ACI.
Rounding: The final ACI value is rounded to one decimal place for better accuracy.
ACI Standardization:
Objective: To simplify interpretation by reducing the ACI to a scale of 0 to 300%.
Normalization Scale:
0-100 ACI: 0-100%
101-200 ACI: 101-200%
201-300 ACI: 201-300%
Above 300 ACI: Capped at 300%
Alert Thresholds:
Thresholds are defined to indicate different air climate levels, allowing rapid assessment of environmental conditions.
Air - sensors taken into account
Ambient air quality monitoring relies on a series of sensors installed in areas.
You can configure the dashboard to display all sensor details, but the quality of information quickly becomes overwhelming.
Here is the list of supported sensors:
Temperature :
Measures ambient temperature in degrees Celsius.
Humidity :
Measures the level of relative humidity in the air, expressed as a percentage.
Carbon Dioxide (COâ‚‚):
Monitors COâ‚‚ concentrations, important for assessing ventilation and indoor air quality.
Suspended Particles (PM):
PM1: Particles with a diameter less than or equal to 1 micrometer.
PM2.5: Particles with a diameter less than or equal to 2.5 micrometers.
PM4: Particles with a diameter less than or equal to 4 micrometers.
PM10: Particles with a diameter less than or equal to 10 micrometers.
Pollutant Gases:
Ammonia (NH₃): Monitors levels of ammonia, a respiratory irritant gas.
Carbon Monoxide (CO): Measures concentrations of CO, a toxic, odorless gas.
Ethanol (C₂H₆O): Monitors levels of ethanol, often emitted by solvents and cleaning products.
Hydrogen (Hâ‚‚): Assesses levels of hydrogen, used in various industrial processes.
Methane (CHâ‚„): Monitors concentrations of methane, a flammable and potentially dangerous gas.
Nitrogen Dioxide (NOâ‚‚): Measures levels of NOâ‚‚, an air pollutant gas.
Nitrogen Oxides (NOx): Monitors combined levels of NO and NOâ‚‚.
Volatile Organic Compounds (VOC): Evaluates the concentrations of VOCs, responsible for various indoor pollutions.
VOC Quality: Measures the quality of VOCs, providing a more detailed assessment of organic pollution levels.
