Gas sensors are devices that measure the concentration of gases or vapors in the atmosphere, and are essential in research, industrial, medical, and environmental safety applications. One of the most advanced and reliable gas sensors available on the market is the VQ21TB, which is high performance, low power consumption, and has a long life span. This article will provide an overview of the application field and working principle of the VQ21TB.

Application Fields of VQ21TB Sensor

The VQ21TB gas sensor can detect a wide variety of gases, including combustible gases such as Natural Gas (CNG) and Liquefied Petroleum Gas (LPG), as well as toxic gases such as Carbon Monoxide (CO), Hydrogen Sulfide (H2S), and Ammonia (NH3). It can also detect other gases such as Methane (CH4), Nitrogen Dioxide (NO2), and Ozone (O3).

This sensor is also widely used in the automotive industry, where it is used to detect emissions of hazardous gases from cars and industrial machinery. It is also used in industrial safety applications, where it can be used to detect hazardous gases in the workplace. It is also used in medical settings, where it can be used to detect potentially hazardous gases in the environment.

In addition to these applications, the VQ21TB gas sensor can also be used in research and scientific experiments to measure the concentration of gases in different environments.

Working Principle of VQ21TB Sensor

The VQ21TB gas sensor works using a chemical reaction process. In the presence of a target gas, the sensor\'s surface is exposed to the gas molecules, which causes a reaction and results in a change in the resistance of the sensor. This change in the sensor\'s electrical resistance is then measured, allowing for the concentration of the target gas to be determined.

The VQ21TB gas sensor is also equipped with advanced features such as selectable gas sensitivity, adjustable sensitivity, and temperature compensation. This means the sensor can be used in a variety of different environmental conditions, and its performancecan be adjusted to suit the specific needs of the application.

Overall, the VQ21TB is a high performance, reliable, and long-lasting gas sensor that can be used in a wide variety of applications. From automotive emissions applications to industrial and medical safety applications, the VQ21TB is the perfect solution for any gas sensing application.
