-Los compuestos orgánicos son sustancias químicas que contienen carbono y se encuentran en todos los elementos vivos. Los compuestos orgánicos volátiles, a veces llamados VOC (por sus siglas en inglés), o COV (por sus siglas en español), se convierten fácilmente en vapores o con el carbono, contienen elementos como hidrógeno, oxígeno, flúor, cloro, bromo, azufre o nitrógeno.
For the continuous monitoring of TVOC, MOS sensors are generally used. This is a broad category, and sensors across this category provide varying degrees of quality in their readings - not all MOS sensors are built equal. Similar technology is used throughout, however, which is what we will explore below:

2021-07-16· The TVOC sensor is, for what you get, quite reasonably priced (it’s currently on for just under €50) and can be found in a few online stores in Sweden. By contrast, the Eve Room (v2), is selling for practically double the price, and as of the time of writing, still uses Bluetooth. Putting that topic to one side, the version I have here today is the Chinese version, hence the ...

TVOC refers to the total concentration of multiple airborne VOC’s present in indoor air from a variety of sources. Using TVOC sensing indoor air quality can be assessed beyond the limitations of using CO2 as a standard metric. TVOC concentrations are up to 10 times higher indoors than outdoors, supporting the need for sensing devices and ventilation strategies as part of the BMS. CO 2 ...

Volatile organic compounds (VOC) are organic chemicals that have a high vapour pressure at room vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility.. VOCs are responsible for the odor of scents and perfumes as well as pollutants.
A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied. In other words, higher levels of CO2 correspond to larger numbers of people inside, and ...
