With an average consumption of 45 μA, the sensor is energy effective and guarantees a minimum of 15 years of measurements with an accuracy of ±(30 + 3%) ppm.
Batteries

Two pre-installed replaceable CR123A batteries provide up to 3 years of battery life without recharging the detector or connecting it to the mains.
SmartBracket

The mounting panel is designed to easily fix the device on a flat surface without disassembling the enclosure. The detector can be removed from the panel with one move to take it with you. A built-in accelerometer notifies if the detector has been removed from the mounting panel or changed its position.

Unique wireless technologies

The Ajax system uses two-way secure radio communication based on Jeweller and Wings proprietary protocols. Radio protocols work in parallel and focus on their own function, guaranteeing instant data and delivery even with communication interruptions and a weak signal.

Ajax wireless technology has up to 1,700 meters of radio signal communication range in an open space, making it on average longer than competing solutions from different manufacturers. Automatic power adjustment makes it energy efficient by not using the maximum power of radio transmitters in system devices on a regular basis. It is also more stable, using less noisy radio frequencies.

Air quality sensor Ajax LifeQuality

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 principle of operation of the indoor air quality sensor from Ajax

The indoor air quality sensor transmits the received data using the Jeweller radio protocol at a distance of up to 1700 meters from the security control panel or signal repeater, provided there are no obstacles. Jeweller technology provides a two-way communication between the air quality sensor and the security control panel and protects devices from forgery by floating key block encryption of the signal. RF hopping is used to prevent interference and jamming of the radio signal. This means that the device will switch to a clean signal when trying to jam the current one.

The indoor air quality monitor has a built-in accelerometer that alerts you if the device has been moved.

The air quality sensor is controlled and configured in the Ajax application for PC or mobile phones. The application also receives instant notifications from the sensor.

The power of the air control sensor is adjustable to reduce power consumption and radio interference.

With optional Wings wireless technology for redundant communication with a security central or radio repeater, data packets are redownloaded in the event of a data transmission error. If the indoor air quality sensor loses communication with the control panel or radio signal repeater, it remembers all measurement values. After the connection is restored, all values will appear in the Ajax application.

Air measurement

The air quality sensor monitors the following three indicators of indoor air quality:

Temperature measurement

Using a sensitive element, a digital combined temperature and humidity sensor measures indicators and transfers them to Ajax applications. The data is updated depending on the polling frequency of the control panel — sensor, but at least once a minute. The temperature is measured in the range from 0°C to +50°C, with an accuracy of ±0.2°C.

Humidity measurement

Humidity indicators in the guarded room are measured using the sensing element of a digital combined temperature and humidity sensor. The user can track the values in Ajax applications and they are updated depending on the frequency of polling the central sensor, but at least once a minute. The measurement range of indicators is from 0% to 100%, with an accuracy of ±1.8%. The received data is available in Device States in Ajax applications.

Measuring the concentration of carbon dioxide (CO2)

The level of carbon dioxide is measured using the sensing element of a digital carbon dioxide sensor. Indicators are updated in Ajax applications depending on the frequency of polling the sensor by the control panel, but at least once a minute. Carbon dioxide indicators are measured in the range from 400 to 5000 ppm with a measurement accuracy of ±30 ppm or ±3%. Data available in Device States in Ajax applications. The levels of air quality assessment in terms of carbon dioxide in the air are as follows:

normal air: up to 1000 ppm
slightly polluted air: 1000 to 1400 ppm
polluted air: 1400 to 2000 ppm
critically polluted air: more than 2000 ppm.

The sensor also measures the impact of indicators on well-being:

from 1000 to 2500 ppm — general lethargy,
from 2500 to 5000 ppm — possible adverse health effects,
5000 ppm and more — the maximum allowable concentration for 8 hours of the working day.

Additional features

Ajax applications provide graphs with indicators of temperature, humidity and carbon dioxide concentration. Values are updated in real time and measurements are stored for up to 2 years. The LED display of the combined air quality sensor reports the current situation in the room with a colour:

green — air is normal
yellow — the air is slightly polluted
red — the air is polluted
purple — the air is critically polluted

The LED indicator on the body of the device lights up in the event of a critical change in air quality. The indication can also be turned on by touching the touch button on the front panel of the sensor. Once every 1-14 days, the air quality sensor is automatically calibrated. The device selects a calibration period depending on the situation in the room and automatically calibrates the carbon dioxide sensor. Under normal conditions, that is, in a room that is ventilated, manual calibration is not needed. Manual calibration is launched in Ajax applications. It is used in unventilated rooms once every 2-3 weeks.

Ajax air quality sensor installation

The air quality sensor is installed on the SmartBracket mounting panel on the ceiling, wall or table of the monitored room.

Air quality sensor package

The kit for the air quality control device includes the sensor itself — LifeQuality Jeweller, SmartBracket mounting panel, 2 pre-installed CR123A batteries that provide up to 3 years of battery life of the device, a mounting kit and a brief instruction.
