Understand ventilation quality and indoor air freshness.
INDOOR AIR QUALITY MONITOR
HibouAir DUO – Smart Indoor Air Quality Monitor
CO2 and particulate matter monitoring in one compact device
HibouAir DUO combines CO2 and particulate matter monitoring with supporting indoor environmental data. It helps users understand both ventilation quality and airborne particle conditions from one compact monitor.
Use it to track indoor air quality in offices, schools, healthcare spaces, commercial buildings and monitoring projects where reliable real-time and historical data are needed.
Dual Sensor Advantage
One device. Complete indoor air quality insight.
Why CO2 and PM sensors work better together
CO2 readings show ventilation quality and help detect stale indoor air early. Particulate matter readings identify airborne particle pollution from dust, smoke, traffic, equipment, or nearby activity. Together, these measurements give facility teams a clearer basis for improving HVAC decisions, filtration strategy, occupancy planning, and day-to-day indoor safety.
What it measures
One device for the indoor parameters that matter
CO2 shows ventilation and air freshness. PM readings show dust, smoke and airborne particles. Supporting measurements add context for comfort, filtration and indoor air quality decisions.
Detect fine and coarse airborne particles from dust, smoke and pollution.
Measure volatile organic compounds affecting air quality and occupant health.
Track indoor temperature levels to maintain comfort and energy efficiency.
Monitor moisture levels to support comfort and prevent mold formation.
Measure air pressure changes to improve ventilation balance and system control.
Capture ambient light levels to enhance comfort and optimize energy usage.
Access continuous data insights for faster decisions and proactive environment control.
DATA LOGGER & REPORTS
Data logger, historical charts and exportable reports
HibouAir DUO helps users go beyond live readings. Stored measurements can be retrieved and reviewed as historical charts, exported as CSV files, and used to generate advanced reports through the mobile application.
For desktop monitoring setups, the desktop application also makes it easy to export reports for projects, inspections and customer documentation.
Local data logging
Store measurements for later review and analysis.
Historical charts
View how CO2, PM, VOC, temperature, humidity and other parameters change over time.
CSV export
Export raw measurements for spreadsheets, analysis or documentation.
Advanced reports
Generate easy-to-share reports with charts and summaries from the mobile app.
Connectivity & System
Industry-ready indoor air quality monitoring
Choose the DUO variant that fits the way your team needs to access air quality data, from local BLE workflows to connected WiFi or cellular deployments.
Flexible Connectivity
BLE, WiFi, and Cellular options support local monitoring, connected sites, and integration workflows.
Lower Device Count
Combine CO2 and particulate matter insight in one device instead of installing separate monitors.
Continuous Monitoring
Designed for always-on operation with stable performance and reliable data delivery.
High Accuracy Sensing
Industrial-grade sensors provide consistent measurements for practical decisions.
MOBILE APPLICATION
Monitor and manage DUO air quality data from your phone
Use the mobile application to view live CO2, PM, VOC, temperature, humidity and pressure data, review historical charts, retrieve stored measurements, export CSV files and generate advanced reports.
Use cases
Smarter indoor environments with CO2 + PM insight
Use HibouAir DUO in offices, schools, healthcare spaces, commercial buildings, industrial spaces, air quality service projects and indoor monitoring projects where both ventilation and particle visibility matter.
