The Ajax LifeQuality (8EU) is a smart air quality meter in white that combines superior measurement accuracy with a modern design and easy integration into a smart home. The device monitors temperature, humidity and carbon dioxide (CO₂) concentrationwith medical-grade accuracy, instantly alerting you to air quality deterioration via LED signalling and push notifications in the app. Thanks to the connection to the Ajax central unit, it is possible to automatically start the ventilation or humidifier if the measured values exceed the set limits. The Ajax LifeQuality (8EU) is designed for home, office and industrial environments and offers maximum flexibility. It can work not only in a fixed location, but also as a portable device - for example, in a hotel room or vehicle. The built-in memory retains data for up to 72 hours without a network connection, and all records are securely synchronized with the Ajax Security System when the connection is re-established. LifeQuality thus provides a continuous overview of the microclimate and helps to maintain a healthy and comfortable environment.


To use the product's smart features, you need to add the device to the manufacturer's app. For more information about the application (name, supported OS, supported languages) and how to add a device to the application, please refer to the product manual.

The Ajax LifeQuality intelligent air quality sensor uses high-end sensors from renowned Swiss and Swedish manufacturers. Temperature and humidity are measured by Sensirion's SHT40 digital sensor with high condensation resistance and an accuracy of ±0.2 °C for temperature and ±2 % for humidity. The carbon dioxide concentration is detected by Senseair's Sunrise optical NDIR sensor, which takes direct measurements without the use of mathematical models and guarantees an accuracy of ±(30 + 3%) ppm. This combination provides users with reliable data for effective microclimate control.

With its compact design and SmartBracket mounting panel, LifeQuality can be easily mounted on a wall or other flat surface and easily removed for transport when needed. The unit can also be used on the move - LED indication provides instant visual information on air quality, while data is recorded in the built-in memory and automatically synchronised when connected to the Ajax system. This allows air control in a variety of environments, from homes to offices to temporary residences.

LifeQuality is not just a passive sensor, but an active part of the Ajax smart ecosystem. In combination with other system elements such as automation relays or switches, scenarios can be set to start ventilation, humidification or air conditioning when set limits for CO₂, temperature or humidity are exceeded. All data is available in the Ajax Security System app for Android, iOS and Windows, including detailed graphs with up to 2 years of history. The operating range of up to 1700 m in open space ensures stable communication even in large buildings.
