The LifeQuality Smart Air Quality Sensor helps you assess indoor air quality. It is important to control humidity levels, CO2 and temperature, as poor air quality has been proven to threaten health and reduce productivity. The sensor from Ajax will provide the accuracy of measuring these indicators at the medical level. The user receives information from the air quality sensor in the application, where he can also set up automation scenarios for the device. Using scripts, the user can control whether the humidifier or ventilation turns on and off if the atmosphere control quality sensor indicates that the air quality can be improved.

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

Measurement accuracy 
±0.2°C

Measurement pitch 
0.1°C 
The minimum temperature change value recorded in the Ajax apps

Humidity measurement

Sensitive element 
Digital temperature and humidity sensor 
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 0% to 100% 
The value is available in the device States in the Ajax app.

Measurement accuracy 
±1.8%

Measurement pitch 
1% 
The minimum humidity change value recorded in the Ajax app.

Carbon dioxide (CO₂) concentration measurement

Sensitive element 
digital carbon dioxide sensor 
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 features

Charts 
of temperature, humidity, and carbon dioxide concentration 
Available 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.

Sabotage protection

Accelerometer 
Notifies on attempts to tear off the detector from a surface, remove it from the mounting panel, or move the detector if it is placed on a table or shelf.

Protection against spoofing 
device authentication

Communication loss detection 
within 36 seconds 
The detection time depends on the Jeweller or Jeweller/Fibra settings.

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.

LifeQuality features in a minute

To help users evaluate the dynamics of air quality, we created LifeQuality, a smart air quality monitor with the carbon dioxide,  humidity, and temperature sensors. It has been proven that poor air quality threatens health, so medical-grade measurement accuracy is always on guard for your productivity at home, in the office, workplace or any other space.

Monitoring everywhere

Private residence

Many daily actions, such as cleaning or cooking a meal, can affect the air quality and cause health problems. LifeQuality provides comprehensive information about temperature, humidity, and CO2, so it's easy to control the optimal microclimate in each room and maintain it for special health conditions. To have a normal temperature in the kitchen or fresh air in a bedroom before sleeping is as easy as breathing now.

Industrial premises

Production operates with standards that require significant accuracy and consistency of every system involved in the process. The micro-climate is essential for safety and production quality, so its indicators must comply. LifeQuality detectors are ready to be a part of a huge climate control system bringing the best of Ajax technologies of long-range communication and outstanding battery life.

Basement and underground facility

As a basement maintenance tool, LifeQuality will keep away condensation and mold by monitoring humidity and temperature level. The ventilation system and dehumidifier can be integrated and automatically react to LifeQuality measurements.

Office

Carbon dioxide levels strongly affect the brain's functioning, hence productivity. LifeQuality is explicitly designed to ensure a healthy working environment to achieve high-quality performance. With Ajax automation devices and scenarios, it's easy to build an automatic climate control system to guard your productivity in every office space.

Kindergarten and school

Polluted air can be quite detrimental and impact children's development during active growth. It affects the learning process by exacerbating fatigue, attention problems, respiratory illnesses, and asthma. LifeQuality detectors and Ajax automation devices, in combination with the HVAC system, can increase the well-being of students and teachers. At the same time, Ajax apps will deliver instant notifications and comprehensive data.

Store

Monitor and control the ideal storage conditions for food, flowers, or pharmaceutical products. LifeQuality will ensure that all products are fresh and well-preserved, giving accurate measurements without deviations. Create a safe working space for staff and keep a comfortable climate for shopping.
