Why to measure CO and NO2?

Sensors in an HVAC environment

Shopping malls, office buildings, large hotels, event venues … Car parks are increasingly important in large building projects. The enclosed atmosphere in an underground car park makes us wonder: how do we keep garages clear from car exhaust fumes?

When cars with combustion engines move around an enclosed parking garage, they release toxic gases like nitrogen dioxides (NO2) and carbon monoxide (CO). Due to the typically low ceiling, underground and enclosed car parks present a particular challenge to ventilation systems. Such a smart ventilation system must prevent the accumulation of toxic from motor exhaust and therefore, it needs a sensor adapted to these conditions.

Sentera designed a special range of sensors for these applications. These devices measure temperature, relative humidity, carbon monoxide (CO) and nitrogen dioxide (NO2) levels as well as ambient light and are available in different enclosure types.
