Gas Sensing Applications

gas sensor applications

Gas sensors are critical for monitoring and detecting hazardous inert gases, and ensuring safety, air quality, or analysis throughout many different industries.

Whether you are looking for a gas sensor that is fast in speed, accurate, low powered, miniature, or easily integrated - the most critical factor in finding the perfect sensor is understanding the environment you intend to measure. 

Did we mention that not all sensors are created equally either?

A sensor that is ideal for measuring indoor carbon dioxide (CO2) levels for indoor air quality will not work to measure concentrations used in fire suppression testing.

One OEM might want I2C protocols, while another individual prefers UART. Some applications require the use of a sampling principle, instead of diffusion.

Furthermore, understanding your application and its requirements is vital in selecting the right sensing technology.

What can a gas sensor detect?

Gas sensors are devices that can detect the presence and concentration of specific gases such as carbon dioxide, carbon monoxide, oxygen and ammonia.
