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.

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.

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.

Industrial premises
Production operates with standards that require significant accuracy and consistency of every system involved in the process. The microclimate 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.

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.

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.

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.

Room for manoeuvre
LifeQuality is easy to carry around, so you can monitor air quality in a hotel room, a friend's house, or even a moving car. LED indication will inform of dangerous air quality wherever you take the detector. Built-in memory allows saving measurements for up to 72 hours without communication with the hub or range extender. And when the connection is restored, all the data is sent to Ajax apps and synchronized with the charts.

• LED indication
• 72 h of the backup memory
• Detailed in-app history

Medical-grade accuracy inside

• LED indicator There is no need to open Ajax apps to determine indoor air quality status. The LED lights up green, yellow, red, or purple depending on the CO2 level. All you need is one tap on the detector's logo.
• Enclosure Thought-out to the smallest detail, the enclosure reflects the placement of sensors inside and has an optimal system of openings for air ventilation. Available in white or black.
• Temperature and humidity sensor SHT40 from Sensirion is a digital sensor from Swiss developers. The sensitive element is designed to work in difficult conditions, such as industrial facilities with a high condensation risk. SHT40 has a self-diagnosis mechanism and provides an accuracy of ±0.2° C for temperature and ±2% for humidity.
• CO2 sensor Sunrise by Senseair is an optical NDIR sensor designed by Swedish developers. It measures carbon dioxide in the air directly without using mathematical models. With an average consumption of 45 μ A, 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.

Charts
Charts show the trend of indicators over the last hour, day, week, month, or year. Ajax Cloud server encrypts and securely stores the air quality history for up to 2 years. The data is accessible at any moment to view, track, and analyze.

Full monitoring for the building
With PRO Desktop, building admin staff can observe not only security but Ajax devices for automation and comfort. Device statuses, event log, and microclimate data - the operator has a complete picture in one intuitive interface, all informative and centralized. The installer can remotely change the settings and provide additional services according to the object specifics.

All-around installation with no wires
LifeQuality does not need recharging or plugging into a power outlet. With a 3-year battery life and no wires, the detector can be installed at any location on the wall or ceiling. Or even used inside a moving car. The batteries are replaceable, so after three years of operation the installer pops the new ones, and LifeQuality continues to operate as usual.

• Up to 3 years of battery life
• Replaceable batteries
• Does not require a power outlet

Advanced microclimate automation
LifeQuality is a part of the Ajax ecosystem and can interact with automation devices, users, and installers through Ajax apps. Scenarios based on LifeQuality indicators can control the microclimate in any room, giving a wide range of appliances to integrate. For example, WallSwitch will turn on heating or ventilation when the specified indicator has reached the limit, and Socket will turn off the humidifier when high humidity becomes uncomfortable.
  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.

• Up to 1,700 meters of radio communication range with a hub
• Encrypted two-way radio communication
• Notifications about jamming and connection loss

Jeweller
The Ajax radio protocol uses polling to display current device statuses and transmits alarms, events, and all the readings into the Ajax apps. Jeweller features encryption and authentication to prevent spoofing.

Wings
Wings is a backup communication channel. Transmits large data packages in case of connection loss and sends data backups from the detector to the hub after restoring the connection.

Scaled and comprehensive
The ReX 2 range extender connects to the hub via radio and Ethernet using the wire as the additional communication channel. This allows covering the most complex objects like a multi-floor office with underground parking or a warehouse with several buildings. ReX 2 avoids obstacles and interference, doubling the radio communication range. Up to 5 range extenders can operate within one Ajax system to expand the network coverage to the stadium size.

• Up to 5 range extenders within one system
• Ethernet as an alternative communication channel

Intuitive installation and connection
LifeQuality is ready to operate straight out of the box. There is no need to disassemble the enclosure. SmartBracket mounting panel allows you to securely install the detector on any flat surface. Ajax apps help quickly make the device a part of the automated system. No need to visit the object to disable the device or change the settings.
