What it is Filled
The amount of water vapour in air or another gas, expressed as absolute humidity in mass per volume, relative humidity as a percentage of saturation at a given temperature, or specific humidity and mixing ratio, and measured with hygrometers; air humidity is a climatic factor affecting comfort, weather, health and materials, and the moisture content of substrates such as compost is an analogous measure in horticulture.
Why it exists Filled
Let an agent explain humidity and its measures, relay measurement, weather and climate roles from meteorological references, describe effects on comfort, health, buildings and materials in general terms, and distinguish humidity from moisture content of solids, dew point and precipitation.
Distinguishing features Filled
- Vapour content
- Temperature dependence
- Several measures
- Wide effects
What robots and AI may and may not do Filled
Must not
- Confuse relative and absolute humidity in reports.
- Set humidifiers or dehumidifiers in a way that causes mould or damage.
- Ignore humidity limits in rooms holding vulnerable people, artefacts or medicines.
- Use home sensor data to infer occupants' habits beyond what they agreed to.
Only with a human decision
- Changing climate control in hospitals, museums or care homes.
May
- Report humidity readings with type, temperature and time.
- Monitor indoor humidity for the household or operator who authorized it.
Moral aspects Filled
- Damp homes cause mould and respiratory illness, especially in children.
- Heat combined with humidity endangers older and ill people.
Who is affected
- Occupants
- Older and ill people
- Collections and archives
Owners Filled
Steward
National weather services for outdoor readings; the occupant or operator for a building.

Plane XCT: no invented physical properties.
Recognition optional Filled
- Water vapour content of air
- Absolute, relative and specific humidity, mixing ratio; compost moisture as an analogue
- Dew point is a temperature; moisture content refers to solids; precipitation is liquid water
- Not a visible object; felt as dampness or dryness.
Capabilities and actions required Filled
- explain measures
- relay measurement and weather role
- describe effects
- distinguish related concepts
Hazards and failure modes required Filled
- Confusing relative and absolute humidity
- Mould and damage at high humidity
- Dryness effects at low humidity
Standards and interfaces required Filled
- WMO measurement standards
- Building and workplace guidance on indoor humidity
- Storage standards for archives and museums
Context of use required Filled
- Not applicable; a state of the air.
- absolute humidity
- relative humidity
- specific humidity and mixing ratio
- indoor humidity
- soil and compost moisture as related measures
Sources Filled
- Wikidata item Q180600: humidity - identity and sense of the item
- Wikipedia: Humidity - general description of the item
Open questions
- Should relative humidity and dew point be separate primary entries?
- How should meteorological references be linked?
- The registry entry has a compost moisture alias that is a different measure; should it be split off?
