Indoor air quality data logging
Indoor air quality data logging and environmental data monitoring
Data logging is the backbone of any serious indoor air programme. Calibrated loggers record CO₂, particulates, VOCs and comfort variables at consistent intervals, building an auditable time-series record that supports investigation, commissioning and reporting workflows.
What the loggers capture
Core indoor environmental data we record
Loggers are selected per parameter — accuracy, resolution and calibration interval all matter for a defensible dataset.
NDIR
Ventilation proxy with traceable calibration.
Optical
Time-resolved particulate counts and mass.
PID
Continuous chemistry proxy.
Comfort
Temperature and humidity time series.
Time-series, not averages
Logging at 1–5 minute intervals preserves the peaks and patterns that hourly or daily averages hide — essential for ventilation and complaint investigations.
Calibrated, traceable loggers
Reference-grade hardware with documented calibration history. Sensors are checked before deployment and post-survey to bracket the dataset.
Exportable datasets
CSV / Parquet exports plus dashboard summaries integrate with BMS, ESG platforms and bespoke analytics.
QC and reporting
Outliers flagged, gaps documented, and a written report contextualises the data against WHO 2021, BS EN 16798-1 and CIBSE TM40 references.
When to use
Where IAQ data logging delivers value
Complaint investigations that need timeline evidence; HVAC commissioning and re-commissioning; ESG and wellbeing reporting cycles; pilot studies before full sensor-system rollouts; and any context where decisions must be defensible against a recorded dataset.
Pairs naturally with continuous air quality monitoring, indoor air monitoring systems and wireless indoor air monitoring.
Benchmarks
Typical logger performance ranges
| Parameter | Range | Typical accuracy |
|---|---|---|
| CO₂ | 0–5,000 ppm | ±30 ppm + 3 % of reading |
| PM2.5 / PM10 | 0–1,000 µg/m³ | ±10 % (vs reference) |
| TVOC (PID) | ppb–ppm | ±15 % of reading |
| Temperature | 0–50 °C | ±0.3 °C |
| Relative humidity | 0–100 % | ±2 % |
| Logging interval | 1–15 min | Configurable |
