Ambient monitoring & air quality
Temperature, humidity and CO₂ should be visible while they rise — not after the complaints. Battery-powered wireless sensors monitor rooms with no cabling; threshold breaches reach the right person as alarms.

What do we measure, and where?
Not every room needs every quantity. The points list follows how each space is used; measurement coverage depends on the sensor model.
| Quantity | Where it matters | How it's assessed |
|---|---|---|
| Temperature | Cold rooms, server and technical rooms, comfort areas | Product range in cold rooms, comfort band in occupied areas; assessed together with how long the deviation lasts. |
| Relative humidity | Archives, storage, comfort areas | 40–60% is the common comfort target; sustained readings above 60% signal mould and material risk. |
| CO₂ | Classrooms, meeting rooms, dense offices | Values staying above 1,000 ppm are the widely accepted sign of insufficient ventilation. |
| TVOC / particulates | Recently renovated or dense indoor areas | Measured with compatible sensors; thresholds depend on the use of the space. |
| Door contact | Cold rooms, technical rooms | A door left open raises the alert before the temperature does (PN Connect dry contact input). |
Threshold values are common guidance; the right thresholds for your spaces are set together at the survey.
A threshold alone isn't enough
Raw values don't create action — values read in context do. In FiotX, ambient data is assessed against your operating pattern.
- Working-hours context: no CO₂ alarm in an empty building at night; rules bind to operating hours.
- Deviation time: a sustained breach alarms, a momentary spike doesn't; false-alarm discipline is preserved.
- Owner and closure: the alarm reaches the right person and is tracked as seen and closed.
- Trends and comparison: similar rooms side by side; the outlier shows itself.
Representative interface · demo data
No cables, no conduits
The sensors are battery-powered and wireless; they go live the same day even in rented buildings, historic structures or spaces you can't shut down.
Battery-powered sensors
No power or data infrastructure; long-life batteries, no installation marks.
In-building coverage
The PN Edge gateway collects sensors over LoRaWAN — floors and basements included.
Commissioned from the platform
Sensor registration and thresholds via FiotX; when a room changes, the sensor moves with it.
Battery & data health
Low battery and data gaps raise platform warnings; no blind spots.
Where does it make a difference?
Classrooms & schools
CO₂ climbs fast in a full classroom; breaks and ventilation are planned on data.
Meeting rooms
Long meetings mean stale air and fading attention; alerts on threshold breaches.
Open-plan offices
Comfort band and indoor air quality; see it before the complaints arrive.
Retail
Comfort on the sales floor; humidity in stock rooms and back areas.
Archives & storage
Continuous temperature and humidity records for sensitive material.
Cold & technical rooms
Temperature, door state and deviation time; nights and weekends included.
Ambient data feeds the HVAC decision
The fix for humidity complaints is usually operating discipline, not a setpoint; the fix for CO₂ is planning fresh air, not throttling the AC. With ambient data and HVAC on the same platform, these decisions are made on data rather than guesses.
If a meeting room breaches its CO₂ threshold every day at 2 pm, the problem is ventilation, not the AC; if temperature is normal but humidity stays high, cooling runtime and airflow are assessed together.
Worth knowing
Around AC and VRF, we also do all of this.
