Gas Sensors: VQ625/3 Application Field and Working Principle

Gas sensors are important to many industries, from medicine and health to the home and building industries. Whether it is indoor air quality or detecting hazardous gas leaks in commercial buildings, understanding the technology of gas sensors can help us address these needs safely and effectively. One of the most popular types of gas sensors is VQ625/3, which is widely used around the world for a range of applications.

The VQ625/3 is a non-dispersive infrared (NDIR) gas sensor that uses light-absorption technology to measure gas concentrations. It is designed to be highly accurate and reliable in measuring carbon dioxide (CO2) concentrations in the atmosphere. It is also capable of detecting other gases, such as methane, but is primarily intended for CO2 detection.

Unlike other gas sensors, the VQ625/3 does not require consumables or hazardous chemicals and has no moving components, making it an ideal choice for industrial applications. It is also effective and durable enough to withstand a wide range of temperatures, humidity, and dust levels. This makes it suitable for both indoor and outdoor applications.

The VQ625/3 operates on the principle of light absorption. When a gas molecule absorbs infrared radiation, its molecules become excited and emit infrared radiation of the same frequency. This is then detected by the sensor, which uses the light absorption process to measure gas concentrations. This is known as Non-dispersive Infrared or NDIR sensing.

The VQ625/3 is designed to detect a wide range of concentrations of CO2. It has a sensing range from 0 to 10,000 ppm and can detect a very small change in CO2 concentration, which makes it suitable for monitoring air quality in homes, commercial buildings, and other indoor spaces.

The VQ625/3 is also capable of detecting some of the gases in the environment, such as methane and other volatile compounds, but this is more of a secondary capability. Its primary purpose is to measure levels of CO2, and it is very effective at this.

The VQ625/3 is an extremely reliable and accurate gas sensor, and its applications are varied. It is used in a number of industries, from healthcare and indoor air quality monitoring to monitoring hazardous gas leaks in commercial and industrial buildings, and even for research purposes.

The VQ625/3 is also popular in the vehicular and automotive industry, where it is used for monitoring the exhaust of emissions from vehicles, as well as for monitoring air quality in vehicles.

The VQ625/3 is an excellent choice for gas sensors. Its accuracy, reliability, and affordability make it ideal for many different applications, from healthcare and safety to automotive and industrial monitoring.
