Features

Intelligent indoor air monitoring

Precise sensors, direct feedback, and flexible connectivity—in a compact wall-mounted or tabletop housing.

Precise CO₂ measurement

CO₂ from 0 to 5000 ppm with auto-calibration – high-quality sensor modules from the DACH region.

Temperature, humidity, pressure

Plus relative humidity, temperature, and air pressure – the complete indoor climate at a glance.

Visual feedback

An LED traffic light system immediately signals air quality and enables users to respond directly.

Audible feedback

Integrated buzzer actively alerts users to critical CO₂ levels – can be turned on and off via NFC.

Multi-connectivity

LoRaWAN®, mioty®, or NB-IoT/LTE-M – compatible with existing infrastructure and coverage.

NFC configuration

Conveniently configure sensor and network settings via smartphone – using the LinQs app for iOS and Android.

Replaceable AA batteries

4× standard AA batteries, easy to replace. Optional AC power operation for shorter transmission intervals.

Double-tap measurement

Two quick taps on the sensor immediately trigger a new measurement with visual feedback.

Benefits

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

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.

Details

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.

Aerosol indicator

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.
