IAQ (Indoor Air Quality)

Gas sensors

Visualizing CO₂ concentration helps understand indoor ventilation conditions and stagnant air, contributing to comfortable and healthy indoor spaces. It can be used in a variety of spaces where people spend time, such as homes, offices, schools, stores, and public facilities.

IAQ (Indoor Air Quality) is an important factor related to the comfort and health of people indoors. In recent years, as homes and buildings have become more airtight, insufficient ventilation can lead to increased CO₂ concentration and air-stagnation.

CO₂ increases indoors through human respiration. Measuring CO₂ concentration can therefore be used as an indicator for understanding occupancy and ventilation status. Visualizing indoor air quality with measurable CO₂ data helps determine appropriate ventilation timing and supports integration with air conditioning and ventilation systems.

What is Required for IAQ

When managing indoor air quality, it is important to understand the invisible state of indoor air. Measuring CO₂ concentration can help address the following issues.

Visualization of insufficient ventilation
Understanding stagnant or poorly circulating air
Occupancy-based ventilation control
User notifications through air quality monitors
Balancing comfort and energy savings

Main Use Cases

Air Quality Monitors

Used to display CO₂ concentration and inform users when ventilation may be needed. It can be used in various indoor spaces, including homes, schools, offices, and stores.

Smart Homes

By measuring indoor CO₂ concentration and connecting with ventilation and air conditioning equipment, it helps create comfortable living environments.

Offices and Meeting Rooms

In spaces where people gather, CO₂ concentration can rise easily. Visualizing air quality makes it easier to understand when ventilation is needed.

Schools and Public Facilities

In spaces used by many people, managing air quality is important. CO₂ concentration measurement can be used to check ventilation status and manage indoor environments.

Portable Measurement Devices

Portable air quality monitors can measure CO₂ concentration regardless of location. They can also be used for simple indoor environment checks and temporary measurements.

What Gas Sensing Enables

Measuring CO₂ concentration not only enables quantitative monitoring of indoor ventilation conditions but also provides clues for identifying stagnant air and uneven ventilation. When combined with air quality monitors and ventilation control systems, it can support appropriate ventilation actions and improvements in indoor environments.
