Air Quality Monitors

Air quality meters: measure CO₂

An air quality meter gives you control over something you don’t always notice immediately: the quality of the air in your home. We spend a lot of time indoors, and indoor air can become polluted by everyday sources such as cooking, showering, cleaning products, household dust, and insufficient ventilation. An air quality meter makes these factors visible, so you don’t have to guess based on how it feels—you can act on real measurements. That’s not only better for comfort (fresher air, less stuffy), but also practical: you can decide more clearly when to ventilate and where airflow tends to stagnate in your home.

Many people use CO₂ as a quick indicator of ventilation: when CO₂ rises, it often signals that air exchange is lagging behind the number of people in the room. Always combine this with common sense and your specific situation (number of occupants, room volume, open windows/vents), but it helps a lot to make ventilation concrete and measurable instead of “by feeling”.

What does an air quality meter measure?

The exact readings depend on the model. In practice, you’ll most commonly see these measurements:

• CO₂ (ppm): an indicator of ventilation / “fresh air” in a room.
• VOC (volatile organic compounds): can rise due to sprays, cleaning products, paint, odours, and cooking.
• Particulate matter (PM): relevant for cooking, dust, traffic pollution (with windows open), and general air pollution.
• Temperature & humidity: useful for monitoring comfort and moisture balance (often included as an extra reading).

How to get the most out of your measurements

An air quality meter is most valuable when you use it as a “decision aid”. Place it in a representative spot (not right next to a window, radiator, or extractor vent) and look at trends: when does CO₂ rise, when do VOC values peak, and how quickly does the room recover after ventilation? Then make it practical with alerts and routines, so your Smart Home works for you—not the other way around.

Practical routines that deliver immediate benefits

• Ventilation moments: an alert when CO₂ rises or air quality drops, so you open windows/vents in time.
• Bathroom/cooking: spot VOC/PM spikes and ventilate or extract faster.
• Maintain comfort: combine with temperature/humidity to keep your indoor climate stable.

Combine smart within Smart Home (recommended)

For a complete picture, combine air quality measurement with other Smart Home building blocks. Start at Smart Home and build from sensors:

• Smart sensors – an overview of sensors and use cases.
• Temperature & humidity sensors – ideal for sharpening comfort and moisture control.
• Smart climate control – to logically combine measuring and adjusting (comfort/savings).
• Smart plugs – useful to smart-switch a fan or air purifier via routines (based on your triggers).
