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)
🟢 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)
🟢 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:
Monitoring
Data
Map
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.
