Double-tap measurement
Two quick taps on the sensor immediately trigger a new measurement with visual feedback.
Why CO₂ monitoring?
CO₂ is a reliable indicator of indoor air quality, concentration ability, and aerosol exposure in indoor spaces.
Healthy indoor climate
Continuous CO₂ monitoring ensures fresh air, concentration, and well-being.
Aerosol & Infection Prevention
CO₂ correlates with the amount of aerosols in the room—a reliable indicator of infection risks indoors.
Smart ventilation control
Threshold-based alerts optimize ventilation cycles and reduce energy loss from unnecessary ventilation.
Compliance & Documentation
Audit-ready measurement data for schools, daycare centers, and workplace regulations—without manual readings.
Flexible placement
Wall mounting, magnets, or simply placing it on a surface—completely location-independent thanks to battery operation.
Quality from the DACH region
High-quality sensors from the DACH region – precise, durable, and calibrated for professional use.
Industries and Applications
Ideal for any setting where people spend many hours in enclosed spaces.
Educational institutions
Schools, universities, and kindergartens – a healthy learning environment and CO₂-based ventilation recommendations.
Offices & Businesses
Office spaces, conference rooms, and common areas – ensuring sustained concentration.
Healthcare
Hospitals, medical practices, and care facilities – reliably monitor sensitive areas.
Retail & Food Service
Stores, restaurants, and cafes – ensuring a comfortable environment for customers and staff.
Real Estate & Housing
Apartments, public buildings, and rental properties – professionally document indoor climate conditions.
Industry & Manufacturing
Production halls, warehouses, break rooms, and cafeterias – Meet occupational safety and compliance requirements.
What makes the Febris CO₂ special
LED traffic light, buzzer, NFC, double-tap, and replaceable batteries—everything a smart CO₂ traffic light needs to do.
Visual feedback
Direct visual feedback via LED traffic lights: green, yellow, red. Users react immediately and take appropriate action.
Replaceable batteries
Four standard AA batteries – easy to replace via snap-lock. Shorter measurement and transmission intervals possible.
Provisioning via NFC
Activation and configuration via NFC. Sensor- and network-specific settings conveniently via the LinQs app.
Audible feedback
Integrated buzzer provides alerts even without visual contact with the traffic light – can be activated via NFC or set to silent.
Power supply
Optionally operable without a battery holder using a power supply – for continuous operation with the shortest transmission intervals.
Double Tap
Two quick taps trigger an immediate measurement. Results are displayed immediately via the traffic light and buzzer.
Air Quality & Virus Transmission
Aerosols in the air we breathe can transmit viruses and bacteria. Especially indoors, air quality is usually poorer than outdoors – increasing the risk of infection. CO₂ concentration correlates with aerosol levels and is therefore a reliable indicator.
- Real-time monitoring: continuous CO₂ measurement in indoor air.
- Warning system: automatic alerts when thresholds are exceeded – prompt to ventilate.
- Data analysis: Evaluation via web app and API – identify patterns, optimize ventilation strategies.
