CO₂ measurement and indoor climate monitoring for occupied rooms

Stuffy classrooms, hot offices or high basement humidity: indoor climate monitoring shows when these conditions occur and how long they last. SECURUS uses suitable sensors to collect CO₂, temperature and humidity readings and shows histories by room and site.

How it works

From the reading to the right person.

01

Measure

Sensors record readings or events directly on site.

02

Transmit

Via LoRaWAN to a gateway within range, then through its internet connection to the platform.

03

Check

The platform checks every value against your thresholds, rules and time windows.

CO₂ in schools and meeting rooms

In classrooms, meeting rooms and group rooms, the CO₂ level shows how well the air exchange matches occupancy. The history shows whether a new ventilation routine is working. CO₂ is only one reading, though; particulate matter or other substances need their own air quality sensor.

A CO₂ traffic light only shows the value on site. With CO₂ measurement in SECURUS, custodians, school management or building management see all rooms in one overview, remotely too. The histories show which rooms are regularly poorly ventilated and help decide where a ventilation system or changed break times are worthwhile.

The AM103 measures CO₂, temperature and humidity and displays the readings in the room. The AM319 adds further air parameters, including particulate matter and a TVOC indicator for volatile organic compounds. Available measurements depend on the device variant.

Keep an eye on room temperature during heat waves

High temperatures affect concentration and well-being, and for older people and young children they can become a health risk. SECURUS shows which rooms heat up and reports exceeded limits at night and on weekends too. This supports the heat protection plans of care facilities, nurseries and schools.

Damp in basements and common rooms

In laundry rooms, drying rooms and basements, humidity trends show when and for how long it is too damp, and whether ventilation or building work is helping. The readings do not detect mold itself or its cause. More under property management.

In summer, warm humid outdoor air can cool inside a basement. Relative humidity rises, and condensation may form on sufficiently cold surfaces. The dew point calculated from room air provides information; the air sensor alone does not show whether a wall reaches that temperature.

Histories support assessment of unusual conditions. Our mold prevention page explains interpretation. A specialist investigates causes such as thermal bridges, ventilation or water ingress; dedicated leak sensors monitor water at risk points.

Air quality in warehouses and production

In warehouses, besides staff wellbeing, the goods are often the concern: paper, wood, food or electronics tolerate neither permanently high humidity nor large temperature swings. Robust temperature and humidity sensors show where heat builds up or moisture collects, also in large halls with several measuring points.

In production and workshops, measuring CO₂, fine dust and other substances helps assess ventilation and work processes. The histories do not replace prescribed workplace measurements, but they show when and where air quality changes.

Measuring air quality and planning indoor climate monitoring

Start with the question you want to answer: whether rooms are adequately ventilated, become too hot in summer or have excessive humidity. This determines the measurements, sensor count and suitable thresholds. Many indoor climate sensors run on batteries and transmit over LoRaWAN. Devices with additional measurements may require an external power supply.

You set the limits yourself, per room and to suit its use. Alerts go by SMS, email and to the dashboard for the responsible group. With schedules you decide whether alerts are only sent during opening hours, for example in a classroom, or around the clock, for example in a basement.

Using indoor climate data in everyday work

Measurement helps most when someone works with the data. In the morning, custodians see which rooms were too warm, too damp or poorly ventilated the day before. Building management recognizes which rooms stand out regularly and can plan measures in a targeted way instead of treating all rooms alike.

Indoor climate and energy belong together: if a window stays open while the heating is on in winter, falling temperatures and high consumption show it. Together with energy monitoring, the histories show where ventilation and heating can be better coordinated.

In practice

Make sense of indoor climate readings

The same number may mean different things depending on the room and its use. Consider trends and measurement location together.

Consider CO₂ alongside room use

A brief peak after a meeting differs from regularly elevated readings lasting hours. Record typical usage and assess whether ventilation changes the pattern.

Humidity and temperature belong together

As air cools, relative humidity increases. A central room sensor also does not describe conditions at every external wall. For unusual basement conditions, mold prevention explains the relationships.

Keep measurement points comparable

Choose suitable locations and keep them consistent when evaluating interventions. Direct sunlight, radiators and windows can significantly affect readings.

FAQ

Frequently asked questions about indoor climate monitoring

What does indoor climate monitoring measure?

Depending on the sensor, CO₂, temperature and humidity, and with extended models also fine dust, volatile organic compounds, air pressure or light. SECURUS stores all values as histories and reports limit exceedances.

Does CO₂ measurement replace a CO₂ traffic light?

It can complement or replace it. With a display in the room, users see the value directly, and all rooms with their histories are also available in the platform.

Does the sensor detect mold?

No. It measures humidity and temperature and so shows conditions in which mold can develop. Whether mold is present and where it comes from is clarified by a specialist on site.

Does every room need a sensor?

Each room you want to assess needs a suitable monitoring point. You can start with rooms that have known issues or heavy use. Large rooms or different climate zones may need several sensors.

Where is the sensor installed?

In the occupied area, not right next to a window, a radiator or where someone breathes directly onto it. We agree the position during planning.

Who sets the limits?

You do, to suit how your rooms are used. The example values on this page are not general limits.
