MEASURED VALUES

The ProxiCube® measures via sensors, reports via display, app and dashboard and documents in the cloud.

CO2-Concentration

Carbon dioxide (CO2) is one of the natural components of the air and is an important greenhouse gas in the earth’s atmosphere. Excessive carbon dioxide concentrations in the interior lead to reduced performance and fatigue. The Federal Environment Agency recommends letting fresh air into the room from outside if a value of 1,000 ppm CO2 is exceeded. Symptoms such as poor concentration or headaches appear long before the indoor air is consciously perceived as bad.

Our defined evaluation of the values for the presentation in the app, on the ProxiCube® display and via the traffic light:

  1. green icon for values from 0 to 1,000 ppm
  2. yellow icon for values from 1.001 to 1.500 ppm
  3. red icon for values from 1,501 ppm

TVOC

(Only in app and dashboard)

Air pollutants are briefly referred to as VOCs. The abbreviation VOC (Volatile Organic Compounds) stands for volatile organic compounds. These are organic-chemical compounds in the boiling range of approx. 50–260 °C. VOCs are contained in room air practically anytime and anywhere.

An increased concentration of TVOC (Total Volatile Organic Compounds) can initially manifest itself in a changed smell and taste perception or irritation of the eyes or mucous membranes. Other effects are poor concentration, exhaustion, dry skin or headaches.

The guide values for the occurrence of TVOC comprise five levels:

  1. ≤ 0.3 mg / m³ – hygienically harmless.
  2. > 0.3–1 mg / m³ – Hygienically harmless as long as no guideline values are exceeded for individual substances or groups of substances.
  3. > 1–3 mg / m³ – Hygienically noticeable.
    Use of rooms that are used regularly is only acceptable for a limited period (<12 months).
  4. > 3–10 mg / m³ – Hygienically questionable.
    Use of rooms that are used regularly is only acceptable for a limited period (<1 month).
  5. > 10 mg / m³ – Hygienically unacceptable.
    Avoid using space if possible. A stay is only permitted for an hourly / limited period per day.

INDOOR AIR QUALITY

Indoor air quality (IAQ)
Under the term indoor air quality or indoor air quality, those aspects of indoor air are considered that have an impact on people’s wellbeing and health. People in Europe spend an average of 90% of their life indoors today. Each person breathes in 12,000 liters of air per day, depending on their age and activity. This is far more than what a person ingests through food (food and drinking water). Against this background, it becomes clear how important the quality of indoor air is for people’s wellbeing.

The IAQ scale ranges from 0 (clean air) to 500 (heavily polluted air). During operation, the algorithms are automatically calibrated and adapt to the typical environments in which the sensor is operated (e.g. at home, at work, in the car, etc.). This automatic background calibration ensures that users experience consistent IAQ performance.

  1. With values from 0–100> IAQ house green
  2. With values from 101–150> IAQ house yellow
  3. With values from 151–200> IAQ house orange
  4. With values from 201–500> IAQ house red

 

Temperature

Temperature

The air temperature has a significant influence on the reaction time of chemical processes and thus on the human metabolic process. Temperatures that are too high or too low can have a negative impact on mental or physical health.

The Federal Environment Agency recommends specific guide values for the room temperature. A distinction is made between the respective uses of the rooms.

We recommend 21–23 °C in living areas. The guide value for children’s and bathrooms is 23 °C, in the kitchen 18–19 °C and in the bedroom 16–18 °C. A room temperature between 21–22° C is recommended for offices.

AIR PRESSURE

Icon Luftdruck
Icon Luftdruck

AIR PRESSURE

The compression, i.e. the compression of the air, is referred to as air pressure. Changes in air pressure are caused by various complex atmospheric processes.

Researchers assume that air pressure fluctuations with an amplitude (oscillation) between 0.3 and 0.5 hPa (hectoPascal) have an impact on blood pressure, circulation and concentration.

If the value falls below 0.73 hPa, the type and duration of the activity must be adjusted for health reasons.

HUMIDITY

Icon Luftfeuchte
Icon Luftfeuchte

HUMIDITY

Air humidity describes the proportion of water vapor in the gas mixture in the air. Relative humidity describes the ratio of the water vapor actually contained in the air to the maximum possible water vapor content.

If the humidity in a room is too low, the breathing capacity is reduced. In addition, dryness can lead to skin irritation and irritation. The mucous membranes can also dry out. Excessive relative humidity can cause discomfort and stress on the circulatory system, as well as impaired productivity. Probably the greatest danger in rooms with too high humidity is the formation of mold. A relative humidity between 40 % and 50 % is recommended in closed rooms.

Sound becomes noise when unwanted noises are perceived as annoying, annoying or impairing. As a psychosocial stress factor, noise exposure can also severely restrict well-being and thus the quality of life. If noises are perceived as a disturbance or annoyance, dissatisfaction and irritation arise. As communication and attention suffer, performance decreases. Sleep disorders can occur especially at night. Mental illness can also be triggered by noise.

In the Federal Immission Control Act TA Lärm, maximum limits are set for indoor spaces (25 dB at night, 35 dB during the day). Outside, other limit values apply to different areas.

DEW POINT

DEW POINT

(Only in app and dashboard)

The dew point is the temperature below which water vapor in the air condenses to form water. At this temperature point the air is completely saturated with water. If the dew point is too high or too low, water can condense, which can lead to mold.

Recommendations for the relative humidity also result in direct recommendations for the dew point. At room temperature, the recommended lower limit of the dew point is approx. 9 °C – below this the air would be perceived as too dry. The upper limit of the dew point is approx. 15 °C – above this the air would be perceived as too humid.
