LifeQuality Lite Jeweller
Wireless temperature and humidity monitor
Coming soon
Essential indoor climate monitoring
LifeQuality Lite Jeweller monitors temperature and humidity at facilities with strict climate requirements. If a threshold is exceeded, the device can trigger automation scenarios to activate humidifiers, HVAC systems, or other equipment to restore the required conditions. The monitor operates on replaceable batteries for years, even in harsh high- or low-temperature environments, requiring minimal maintenance. Readings and configuration are available at any time in the intuitive Ajax app interface.

Automation in support of compliance
In facilities where climate control is critical, LifeQuality Lite Jeweller not only detects deviations, but also triggers automation scenarios to respond immediately. The monitor can activate humidifiers, heating, ventilation, or other equipment through automation scenarios to restore the required conditions before any damage occurs. The scenarios can be easily created and managed in Ajax apps, and will still be executed if the system goes offline.

Always in control with Ajax apps
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.
Discover future-proof hardware
Climate status is visible at any time without opening Ajax apps. A tap on the monitor's logo reveals whether conditions are normal: green indicates acceptable values, and yellow signals deviations.
Built for demanding environments, the device operates within a range of –22 °F to 122 °F. Its ventilation openings ensure stable performance in areas with a high risk of condensation. The device is available in black or white.
Powered by the SHT40 digital sensor by Sensirion (Switzerland), the device delivers accurate climate monitoring down to ±0.36 °F and ±2% humidity.
Two pre-installed replaceable CR123A batteries provide up to 5 years of autonomous operation without recharging or connecting the device to the mains.
The mounting panel simplifies device installation, requiring only a few steps and no enclosure disassembly. A built-in accelerometer detects device detachment or dispositioning.
Long-lasting autonomy in heat and cold
LifeQuality Lite Jeweller is ready to operate in various environments — from freezers to hot boiler rooms — straight out of the box. The device comes with pre-installed, tested batteries designed for years-long operation. Battery status is always visible in Ajax apps. Months before the batteries are completely discharged, users and monitoring companies receive low battery notifications. This ensures timely maintenance with no service gaps.
