Air Quality & Co2

This dashboard provides insights into the data from the Air Quality(mg/m3) and Co2(ppm) Sensor. The charts are based on data representing the average value per day for each resource.

Overview

The Air Quality and CO2 dashboard tracks two complementary indoor-air metrics: CO₂ concentration (a proxy for ventilation effectiveness and occupant alertness) and the Air Quality Index / TVOC (volatile organic compounds and general air quality). Both are measured continuously by your sensors and graded against established health thresholds.

Use this dashboard to:

  • Monitor ventilation effectiveness and indoor-air health

  • Identify rooms where occupants are likely to experience drowsiness or headaches

  • Provide evidence for HVAC tuning and ventilation upgrades

  • Demonstrate environmental commitment to staff and visitors

Scoring Bands

CO₂ (ppm)

Band
Range
Meaning

🟢 Excellent

< 800 ppm

Fresh air; full cognitive performance

🟡 OK

800–1200 ppm

Acceptable; cognitive performance begins to decline above 1000 ppm

🔴 Poor

≥ 1200 ppm

Drowsiness, headaches, reduced concentration

Air Quality Index (TVOC)

Band
Range
Meaning

🟢 Excellent

< 0.3

Clean air

🟢 Good

0.3–1

Minor pollutants, no concern

🟡 OK

1–3

Noticeable; ventilate

🟠 Poor

3–10

Headaches and irritation likely

🔴 Bad

≥ 10

Health risk; immediate action required

Dashboard Structure

The dashboard is organised into four tabs:

  1. Monitoring

  2. Data

  3. Map

  4. Floor Heatmap

A metric switcher toggles every chart between Air Quality and CO₂.

Tab 1 — Monitoring

Air Quality Trend

Line chart with Daily / Weekly granularity tabs.

Air Quality Index over time, with coloured background bands marking the Excellent / Good / OK / Poor / Bad zones.

Average Air Quality by Resource

Horizontal bar chart, ranked.

Each resource ranked by its average reading, colour-coded by the band the average falls into.

Average Air Quality by Weekday

Bar chart.

Air quality averages per day of the week.

CO₂ Trend

Line chart with Daily / Weekly granularity tabs.

CO₂ concentration (ppm) over time, with background bands at 800 and 1200 ppm.

Average CO₂ by Resource

Horizontal bar chart, ranked.

Resources ranked by average CO₂ concentration, colour-coded by band.

Use it to: find the rooms whose ventilation is most likely overloaded.

Average CO₂ by Weekday

Bar chart.

CO₂ averages per day of the week.

Use it to: validate ventilation behaviour at peak attendance days.

Tab 2 — Data

Air Quality Data Table

Sortable data grid.

Minimum, maximum, and average Air Quality Index readings per resource with timestamps.

CO₂ Data Table

Sortable data grid.

Minimum, maximum, and average CO₂ readings (ppm) per resource.

Both tables support CSV export.

Tab 3 — Map

Sensor Map View

Interactive geographic map.

Buildings plotted on a world map, colour-coded by overall air-quality status.

Tab 4 — Floor Heatmap

Air Quality Floor Heatmap

Colour-coded overlay on an interactive 2D floor plan.

Each monitored resource is shown as a heat point coloured by its current band, allowing you to see at a glance which areas of the floor have ventilation issues.

Filters & Controls

  • Building, Floor, Resource, Resource Type

  • Date range with presets and custom ranges

  • Granularity tabs on trend charts

  • Metric switcher: Air Quality / CO₂

Tips

  • CO₂ tracks occupancy closely — a room with high CO₂ at low occupancy indicates a real ventilation issue, not a busy room.

  • Compare CO₂ peaks against the Reservation Sensor Insights tab in Space Usage to identify specific meetings during which conditions degraded.
