[0002] Gas emission detection and warning devices are specially designed to monitor and warn of gas emissions in the environment. They can be used in a variety of situations, such as industrial production, laboratories, automobile exhaust monitoring, and greenhouse gas emission monitoring. Nitrogen oxide (NOx) emission monitoring is an important part of the environmental and industrial control fields, aiming to reduce the impact on the environment and ensure compliance with relevant laws and regulations. Gas extraction detection is one of the common technologies for monitoring nitrogen oxide (NOx) concentrations in the environment.

[0003] A nitrogen oxide emission warning device generally includes a suction component for sucking gas and a nitrogen oxide sensor for monitoring nitrogen oxide emissions. Once the concentration of nitrogen oxides reaches or exceeds a preset threshold, a warning light will be activated to alert the staff.
