VOCOO+

The guardian of indoor room air: VOCOO+

The VOCOO+ is an IAQ sensor (Indoor Air Quality) for monitoring the ambient air in indoor environments. It can be used for assessing the concentrations of CO2, particulate matter, as well as CO present in the ambient air. Moreover, parameters such as air temperature and relative humidity, as well as a TVOC indicator (total volatile organic compounds) round off the types of measurements available.

The clearly visible LED “red-amber-green“ evaluation indicator system and display guarantee good readability. In cases where the maximum CO2 level is exceeded, the VOCOO+ will indicate the need to ventilate the room.

The IAQ-CO2 sensor for monitoring indoor ambient air hygiene (IAQ) - VOCOO+

Whether it’s in the office, school or living environment, the indoor ambient air sensor conti- nuously monitors the essential components of indoor ambient air. The device will automatically indicate when ventilation is required by simply lighting up the LED “red-amber-green“ evalua- tion indicator. A digital display shows CO2, particulate matter, TVOC, air temperature, relative humidity and CO. The solution also uses an audible acoustic warning signal.

The corona virus can spread widely and quickly as an aerosol, especially in closed rooms. Thus, the potential risk of infection increases. A recent scientific study presented an interesting correlation regarding the concentration of CO2 and the estimated aerosol concentration.
The study carried out by researchers at the Hermann Rietschel Institute of the TU Berlin is based on the assumption that humans are the main source of CO2 and aerosols. However, other emission sources such as supply air, exhaust air, sedimentation and the expiration of viruses were also taken into account.

In order to evaluate the results of their measurement, the researchers set a basic concentration of climit = 3000 viruses. The reason for this being that the risk of infection only exists above
a certain concentration of virus-contaminated aerosols. They assessed the risk of infection to be more critical if the virus concentration was high for a short period of time, than if a person stayed in a less contaminated environment for a longer period of time. The simplified equation is: high CO2 concentration = high aerosol concentration = high risk to get infected with the corona virus.

The correlation between the concentrations of CO2 concentration and the assumed con- centration of aerosol examined in the study confirmed the importance of adequate room ventilation: freshly supplied air reduces the carbon dioxide concentration in rooms and thus
the potential risks of infection. However, since people are very poor at assessing a prevailing CO2 concentration, an objective assessment would prove to be interesting. This is exactly where our VOCOO+ comes into play: using the VOCOO+ the concentration of carbon dioxide in rooms can be detected extremely well. Good reference points are the ASR 3.6 as well as the Pettenkofer number.
