People spend more than 90% of their lives indoors, and the impact of indoor air quality on people is even more crucial. With the continuous development of market economy and science and technology, the construction field is also developing with each passing day. People have higher and higher requirements for the quality of life, and the standards of building decoration and decoration have also increased, so the phenomenon of indoor air pollution has also arisen. VOC is one of the main sources of indoor pollution. Using the Home assistant voc sensor to detect indoor air is an important guarantee for your own health.

 

What are VOCs?

VOC stands for Volatile Organic Compounds. The U.S. Environmental Agency (EPA) defines VOC as any carbon-containing compound that participates in photochemical reactions in the atmosphere, except carbon monoxide, carbon dioxide, carbonic acid, metal carbides, carbonates, and ammonium carbonate.

 

The hazards and sources of VOCs

When VOC reaches a certain concentration in the indoor air, people will start to feel headaches, nausea, and weakness in the limbs; if they continue to stay for a long time, it will damage the liver, kidneys, brain, and nervous system, and may even cause convulsions, coma, memory loss, and There will be serious consequences. The harm of VOC is so serious, but where does it come from? Experts point out that building materials such as walls, ceilings, and floors, as well as decorative materials such as latex paint, wallpaper, insulation materials, and adhesives are the main sources of VOC. It should be pointed out in particular that the VOC of latex paint, which is most commonly used in decoration, mainly comes from the VOC of raw materials, including formaldehyde, ammonia, ethylene glycol, etc., so it is crucial to control the VOC content of raw materials!

 

Why is the VOC sensor a home assistant?

Detection technology is an indispensable and important technical means for people to understand and transform the world. Sensors are an important tool for the development, acquisition, transmission and processing of information resources in activities such as scientific experiments and industrial production.

 

The VOC gas sensor is a device that can sense the concentration of VOC gases in the home. When the VOC concentration in the home is too high, it will send out an audible and visual alarm to remind us to ventilate in time to improve indoor air quality. The Home assistant voc sensor plays an important role in the health of residents.

 

 

How VOC gas sensors work

The working principle of the Home assistant voc sensor is based on chemical adsorption and electrical measurement. The sensor usually contains a material that can adsorb VOC molecules. When VOC molecules enter the sensor, they will chemically react or adsorb with the adsorbed material, causing the sensor resistance to change. This change is proportional to the VOC concentration, and the concentration of VOC in the air can be determined by measuring the resistance change.

 

The VOC gas sensor is an important gas detection device. It is based on chemical adsorption and electrical measurement principles and can quickly and accurately detect the VOC concentration in the air. It not only plays a role in household air environment monitoring, but also has extensive applications in industrial production process control and environmental pollution monitoring. By scientifically and rationally selecting adsorption materials and optimizing the sensor structure, the performance and stability of VOC gas sensors can be further improved. With the continuous advancement of technology, the application prospects of VOC gas sensors will be broader.
