Ajax LifeQuality Jeweller
Wireless temperature, humidity, and CO₂ monitor
Guarding productivity
LifeQuality Jeweller monitors temperature, humidity, and CO2 levels in environments where air quality directly affects comfort and performance. Users get medical-grade measurement accuracy, instant notifications, and detailed in-app insights. If a threshold is exceeded, the device can trigger automation scenarios to activate humidifiers, HVAC systems, or other equipment to restore the comfortable conditions. Readings and configuration are available at any time in the intuitive Ajax app interface.

Medical-grade accuracy inside
LED indicator
Air quality status is visible at any time without opening Ajax apps. A tap on the monitor's logo reveals whether conditions are normal thanks to a green, yellow, red, or purple indication.
Enclosure
Thought-out ventilation openings ensure stable performance in areas with a high risk of condensation. The device is available in black or white.
Temperature and humidity sensor
Powered by the SHT40 digital sensor by Sensirion (Switzerland) with a self-diagnosis mechanism, the device delivers accurate climate monitoring down to ±0.2 °C and ±2% humidity.
CO₂ sensor
Using a Sunrise optical NDIR sensor by Senseair (Sweden), the device measures carbon dioxide directly in the air without relying on mathematical models. With an average power consumption of 45 μA, the sensor is highly energy-efficient and ensures at least 15 years of operation with an accuracy of ±(30 + 3%) ppm.
Batteries
Two pre-installed replaceable CR123A batteries provide up to 3 years of autonomous operation without recharging or connecting the device to the mains.
SmartBracket
The mounting panel simplifies device installation, requiring only a few steps and no enclosure disassembly. A built-in accelerometer detects device detachment or dispositioning.
Always in control with Ajax apps
| Charts | Push Notifications | Remote configuration | Automation scenarios |
| Use a dedicated chart in Ajax apps to track indoor climate and spot deviations at a glance. The chart displays temperature and humidity trends over the selected period: last hour, day, week, month, or year. Measurement history is securely stored and readily available in the apps for up to two years. | Stay informed about any abnormal changes in temperature or humidity without delay. The system sends push notifications as soon as a set threshold is exceeded with precise details, such as time, location, and the triggered device. When set as alarms, the events can also be forwarded to monitoring stations. | Adjust thresholds, LED indication, notification settings, and automation scenarios remotely in Ajax apps. Configuration and maintenance take just a few taps, with no need for on-site visits. | Create and configure an automation scenario in just a few minutes — remotely or on-site. An automated chain of actions works even if the system loses internet connection. |
