# Leitenberger LQM01.1_LR Carbon Dioxide (CO2) Measuring Device \u2013 Air Quality Indicator Light<\/p>\n
The Leitenberger LQM01.1_LR type carbon dioxide meter, also known as a CO2 traffic light, is the ideal solution for anyone who wants to proactively monitor and improve their indoor air quality. This extremely compact and precise device provides real-time feedback on the room's CO2 concentration, giving clear visual indication when ventilation is necessary.<\/p>\n
## Main Features and Advantages<\/p>\n
This device combines the latest technology with a user-friendly design, ensuring reliable and fast information about the state of indoor air.<\/p>\n
### Real NDIR Sensor for Reliable Measurement<\/p>\n
One of the most important distinguishing features of the Leitenberger CO2 indicator light is the use of a **real NDIR (Non-Dispersive Infrared) based CO2 sensor**.<\/p>\n
* **Outstanding Accuracy:** NDIR technology guarantees extremely precise and stable measurement, unlike cheaper equivalent sensors.
\n* **Exclusion of Environmental Influences:** This sensor does not react to solvents or disinfectants that could distort the readings of other sensor types. This ensures that the displayed value exclusively reflects the carbon dioxide content of the air.
\n* **Long Lifespan:** Sensors based on the latest **CMOSens\u00ae technology** ensure a long service life and consistently precise performance.<\/p>\n
### Intuitive Visual Feedback<\/p>\n
Instant measurement of air quality is made possible by the four different colored LED indicators, which function according to the principle of a \u201ecarbon dioxide traffic light\u201d:<\/p>\n
* **Quick Overview:** The user can assess the condition of the room at a glance and immediately know when intervention is necessary.
\n* **Ventilation Recommendation:** The color coding provides clear guidance for optimal ventilation timing.<\/p>\n
### Compact Design and Flexible Operation<\/p>\n
The device is designed to be discreetly integrated into any environment, whether it's a home living room, an office, or a classroom.<\/p>\n
* **Extreme Portability:** With a height of only **under 5 cm**, it is extremely slim, fits easily into any bag, and is thus ideal for mobile use.
\n* **Discreet Placement:** Its small size allows it to be placed unobtrusively in living spaces and workplaces.
\n* **Power Supply Flexibility:**
\n* **USB Connection:** Can be connected directly to any USB power source (mains adapter, computer, etc.).
\n* **Mobile Operation:** Can also be operated with a power bank, ensuring maximum flexibility.
\n* **Battery Option:** The device is also available in a separately purchasable battery version for use independent of a mains connection.<\/p>\n
