Commercial indoor air quality monitoringSee the air in every room you manage.
OMNI Sentinel is a wireless indoor air quality monitor for offices, schools, hotels, healthcare and industrial sites. It tracks CO₂, VOCs, particulates, temperature and humidity in real time and alerts your team when a space drifts out of range.
Real-time air data, not guesswork.
Measures what matters
True CO₂, total VOCs, PM1.0, PM2.5 and PM10, temperature, relative humidity and an air quality index, from one wireless device.
Alerts when it drifts
Set thresholds by room or building. When CO₂ climbs in a packed conference room or humidity stays high in a basement, your team hears about it first.
Shows the trend
OMNI Cloud charts every reading over time and across buildings, so facilities teams can spot ventilation and moisture problems and prove when they’re fixed.
One device, many jobs.
Ventilation insight
CO₂ is a practical stand-in for how well a space is ventilated for the number of people in it.
Moisture & comfort
Humidity and temperature trends help you get ahead of comfort complaints and conditions that can lead to mold.
Specialty gases
Add sensors for carbon monoxide, formaldehyde, nitrogen dioxide, ozone, ammonia and more where a space needs them.
Works with your BMS
Integrations with BMS/HVAC systems, plus an open REST API and webhooks, put air data where your team already works.
Sentinel is an environmental monitor, not a medical device, and it does not detect viruses or diagnose health conditions.
Air quality monitoring by industry
Industrial & mechanical spaces
Monitor plants, data rooms and battery rooms for changing conditions alongside your EHS program.
Hotels & resorts
Air quality guests can feel, plus smoke and vape detection in the same unit.
Commercial & residential portfolios
Humidity, CO₂ and particulates across every property from one dashboard.
Healthcare & senior living
Humidity, VOC and particulate trends in non-clinical spaces.
Schools
Classroom CO₂ and comfort data to support facilities planning.
Public buildings
Environmental visibility across government facilities.
Indoor air quality monitoring questions
What does an indoor air quality monitor measure?
OMNI Sentinel measures true CO₂, total VOCs, particulates (PM1.0, PM2.5, PM10), temperature, relative humidity and an air quality index. Specialty gases such as carbon monoxide, formaldehyde and ammonia are available as add-ons.
Why monitor CO₂ indoors?
CO₂ rises as people breathe in a space, so it’s a practical indicator of whether a room is getting enough fresh air for the number of people in it.
Can it alert me to humidity problems?
Yes. You can set humidity thresholds so your team is alerted when a space stays too damp, which helps you get ahead of moisture and comfort problems.
Does it connect to our building management system?
Sentinel supports BMS/HVAC integrations, an open REST API and webhooks, so readings and alerts can flow into the systems your facilities team already uses.
Do I need a separate vape detector?
No. Every Sentinel includes smoke, vape and THC detection along with air quality monitoring in the same device.
Is it a medical device?
No. Sentinel is an environmental monitor. It does not detect viruses or diagnose health conditions.
