Track indoor CO2 levels to understand ventilation quality, occupancy impact and air freshness.
CO2 Sensor BLE – Indoor CO2 Air Quality Monitor
CO2 monitoring with supporting indoor environmental data
HibouAir CO2 Sensor BLE is a compact indoor air quality monitor designed to help users understand ventilation quality and air freshness in real time. It measures CO2 and supporting indoor parameters so teams can see how occupancy, ventilation and room conditions affect the indoor environment.
Along with CO2, the device also measures VOC, temperature, humidity, pressure and light, giving useful context around indoor air quality changes.
One device for CO2 and indoor environment visibility
CO2 is the main measurement, supported by environmental data that helps explain why indoor air quality changes.
Understand changes related to odors, chemicals and indoor emissions that affect air quality.
Monitor indoor temperature levels to understand comfort conditions and environmental changes.
Track relative humidity to detect dry or humid conditions that affect comfort and indoor air quality.
Measure ambient pressure changes to support environmental analysis and indoor condition tracking.
Detect ambient light levels to provide additional context about room usage and environmental conditions.
Understand ventilation before air quality becomes a problem
CO2 levels rise when people occupy a room and ventilation is not keeping up. Monitoring CO2 helps users understand when indoor air is becoming stale, when ventilation may need improvement, and how occupancy affects indoor air quality.
With real-time CO2 readings, teams can compare rooms, identify poor ventilation patterns, support comfort decisions and create healthier indoor spaces in offices, schools, meeting rooms, healthcare areas and shared environments.
Go beyond live CO2 readings with stored air quality data
HibouAir CO2 Sensor BLE is useful for both quick checks and longer monitoring projects. Stored measurements can be retrieved and reviewed as historical charts, exported as CSV files, and used to generate advanced reports through the mobile application. In desktop monitoring workflows, the desktop application can also export reports for inspections, projects and customer documentation.
Local data logging
Store CO2 and environmental readings inside the device for later review.
Historical trend view
Review how CO2, VOC, temperature, humidity and other values change over time.
CSV export
Export raw measurements for spreadsheets, analysis and documentation.
Advanced reports
Generate easy-to-share reports with charts and summaries from the mobile app.
Ready for standalone indoor CO2 monitoring
Designed for practical indoor use, the CO2 Sensor can be placed in offices, classrooms, meeting rooms, workshops or service projects without complicated installation.
