Measurement you can defend.
A spot check cannot defend a room. If a parent, a regulator or an insurer asks what people were breathing at a given hour, you need the named space, the readings at that time, and what was done about them.
Measurement you can defend is continuous, taken where people actually breathe, across the parameters that drive harm. It is not a weekly average, and it is not a number without a time and a place.
Particulates, across the full spectrum
Particle size decides how deep a particle travels, so we resolve four fractions rather than reporting a single number. Every fraction is measured continuously and held against the same timestamp.
Coarse dust, pollen and road grit. Caught in the nose and throat.
The respirable fraction under ISO 7708, reaches the lower airway.
Fine particles that reach the deep lung. The regulated health metric.
Ultrafine combustion and smoke particles that cross into the blood.
Carbon dioxide
Ventilation proxy with direct links to cognition and comfort.
Volatile organics
Solvents, cleaning agents and process emissions.
Nitrogen oxides
Combustion markers for traffic and industrial exposure.
Humidity
Mold windows, comfort bands and clinical ranges.
Dew-point context
Surface and leaf conditions that unlock growth.
Air changes
Delivery evidence for healthcare and dense occupancy.
Sense → Understand → Act
Sense
Deploy sector-appropriate sensors at the resolution that matters, room, bay, house or line.
Understand
Models add outdoor context, occupancy and thresholds so spikes mean something.
Act
Take the action. The Air Ledger holds both sides of the event: what entered the air, and what cleared it.
An immutable record of debit and credit in the air.
A debit is what entered the space: smoke, occupancy, a failed damper. A credit is what left it: ventilation, filtration, an action that recovered the reading. Those events are held as they happen, so you can produce the history later.

What continuous monitoring does
With SensusAir
DrWhat continuous monitoring brings in.
- Each reading is written down as it happens.
- Air shifts. Aeris tells you your next move.
- Every room scored against your standards, live.
- Proof on demand for a parent, auditor, or insurer.
You see the invisible.
Without SensusAir
CrWhat you lose when the air is not watched.
- You rebuild the story after something has already gone wrong.
- Complaints arrive before data does.
- One annual check pretends to cover 364 days.
- Proof is a panicked dig through old folders.
Invisible until it hurts.
Balance the books before the air audits you.
