NO2 Konvertör Alarmı is a Chrome add-on developed to address the issue of not receiving any alarms through the Ministry of Environment, Urbanization, and Climate Change's Continuous Emission Monitoring System. This add-on specifically alerts users with a sound notification when the NO2 Converter Alarm is triggered, aiming to prevent data loss and ensure timely actions are taken upon detection of any issues.

The add-on works by monitoring for the NO2 Converter Alarm and creating an audible alert to prompt users to identify and resolve any malfunctions promptly. It complements the "Data Sending Control" add-on previously created by the developer to prevent data from being marked as "Invalid Data" in case of an NO2 Converter Alarm, thus preventing data loss.
