LIFE QUALITY BLACK

Part Number: AJ-LIFE-QUALITY-B Categories ,

LifeQuality Jeweller is a wireless air quality detector. Measures temperature, humidity, and CO2 (carbon dioxide) concentration in the room. Reports air pollution using an LED indicator and notifications in Ajax apps, enables automation scenarios.

Guarding your productivity

Poor air quality threatens health and reduces productivity. It has been proven that high concentration of carbon dioxide (CO2) causes apathy and drowsiness and reduces the ability to make important decisions by more than 50%.

LifeQuality is a smart air quality monitor with temperature, humidity, and CO2 sensors that helps evaluate air quality dynamics at home, in the office, workplace, or in any other space. Users get medical-grade measurement accuracy, comprehensive in-app information, and automation scenarios. An Ajax system with LifeQuality and automation devices turns on the ventilation or humidifier if the air quality indicators are differing comfortable.

Values in the Ajax apps are updated depending on the frequency of the “hub—detector” polling interval, but not less than once per minute.

 

Measurement range

from 400 to 10,000 ppm

The value is available in the device States in the Ajax app.

 

Air quality assessment levels
normal air: up to 1000 ppm moderately polluted air: from 1000 to 1400 ppm
polluted air: from 1400 to 2000 ppm critically polluted air: more than 2000 ppm

Effects on well-being:
from 1000 to 2500 ppm— lethargy;
from 2500 to 5000 ppm—possible adverse health effects;
5000 ppm and above—the maximum permissible concentration during an 8-hour working day.

 

Measurement accuracy
±30 ppm or ±3%
When the CO₂ concentration is less than 5,000 ppm. For higher concentrations, the measurement error increases.

Measurement pitch
1 ppm
The minimum value of the change in carbon dioxide concentration recorded in the Ajax app.

 

Additional featuresCharts
of temperature, humidity, and carbon dioxide concentrationAvailable in the Ajax apps. The data is updated in real time. Measurements are stored for up to 2 years.
Discrete value: 1 minute.LED indication
green: Normal air
yellow: Slightly polluted air
red: Polluted air
purple: Сritically polluted air

The LED indicator on the device enclosure lights up in the event of a critical change in air quality. The user can also turn on the indication by touching the touch sensitive button on the front panel of the detector.

 

Automatic calibration
once every 1–14 days
The detector selects a calibration interval depending on the circumstances and automatically calibrates the carbon dioxide sensor. In normal conditions (ventilated room), manual calibration is not required. The digital humidity and temperature sensor does not require additional calibration.

Manual calibration

is run in the Ajax apps. Suitable for unventilated rooms. We recommend calibrating the detector once every 2-3 weeks in such rooms.

 

Scenarios

reactions to changes in temperature, humidity, and carbon dioxide concentration

For example, turning on plenum ventilation if the air quality deteriorates.

 

Backup memory

up to 3 days

If the detector loses communication with the hub (or radio signal range extender), it stores all measured values. After the connection is restored, all values are sent to the Ajax app.

 

RecommendationsThe device is designed only for indoor installation at any height. It is not necessary to use the SmartBracket mounting panel.
The detector can be placed on a table or shelf.
