Air quality refers to the state of the air, i.e., the concentration of a mixture of gasses in a given volume. It consists of particulate matter, gasses and vapors, volatile organic compounds (VOCs), ozone, nitrogen oxides, and carbon monoxide.

In this article, we will talk about how the TVOC sensor is used to measure or monitor the VOCs (volatile organic compounds) emissions in the air quality and its applications in different industries.


What Is TVOC Air Quality?

The Air Quality Index (AQI) is based on the number of pollutants present in the air at a specific location. The total concentration of VOCs in the air is commonly referred to as TVOC (Total Volatile Organic Carbon). The total volume of gasses (TVOC) and the volume of gasses per classification (VOC) are significant indicators of the relevant organic compounds present in indoor air. This makes it simpler to determine the overall presence of the VOCs and is much cheaper than other devices measuring individual VOCs present in the air.

However, you need a high-quality TVOC sensor to measure or monitor the total volume of gasses.


What Is In TVOC?

Volatile organic compounds can originate from various places, both natural and man-made, including some environmentally hazardous substances. The following are just a few of the thousands of substances that can cause poor air quality:


  • Benzene
  • Formaldehyde
  • Xylene
  • ethanol glycol
  • Toluene with methylene chloride

Where Can We Apply the TVOC?

VOCs have numerous negative direct and indirect effects on people and various industries. Through toxicity and carcinogenicity, it can lead to material damage in the production environment, the formation of tropospheric photochemical oxidants, etc., and most importantly, it has detrimental effects on human health. That’s why a TVOC sensor is used in different industries to ensure that the environment is safe and ideal for production.

The TVOC sensor is a non-contact sensor that measures the concentration of Volatile Organic Compounds (VOCs) in the air. It is applicable to monitor VOCs in the environment during production processes or for regular quality control purposes. It can be applied in a variety of industries, such as factories, air purifiers, household appliances, and new fans, such as:


Factory Environment:

The TVOC sensor is an excellent choice for measuring CO levels in industries such as factories and workshops, which use large quantities of gas or other flammable substances that could harm workers if not terminated properly.

Air Purifiers:

The TVOC sensor can be used in air purifiers to detect the amount of CO2 in the atmosphere, which helps ensure there is enough oxygen for occupants.

Home Appliances:

These sensors can be used in home appliances to detect their working status and control them accordingly. For example, some high-end refrigerators use gas sensors to detect gas emitted by spoiled food and evaluate the freshness of food items and alert you when the TVOC level is higher than it’s supposed to be.

New Fans:

The TVOC sensor can be applied to new fans to monitor their working status and control their functionality accordingly when needed.

What Is the Safe Level of TVOC?

Once you have begun gathering VOC measurements, you will need a way to analyze the data and determine if the measured levels indicate a volatile organic compound problem in your indoor environment. The TVOC should be below 0.3 mg/m3 or 300 ug/m3 for the environment to be safe. However, a TVOC of up to 0.5 mg/m3, or 500 ug/m3, is still acceptable.
