Ajax LifeQuality Lite Jeweller
Wireless temperature and humidity monitor
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
| Charts | Push notifications | Remote configuration |
| 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
LED indicator
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.
Enclosure
Built for demanding environments, the device operates within a range of –30 °C to +50 °C. Its 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), the device delivers accurate climate monitoring down to ±0.2 °C and ±2% humidity.
Batteries
Two pre-installed replaceable CR123A batteries provide up to 5 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.
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.
- Up to 5 years of autonomous operation
- High-performance batteries from proven manufacturers
- Early low battery notifications
- Easy battery replacement within minutes
Unique wireless technologies
In Ajax systems, communication between wireless devices is powered by proprietary technologies unmatched in the industry. Jeweller ensures reliable alarm and event transmission backed by encryption, frequency hopping, and outstanding energy efficiency. Wings complements it by ensuring data backups reach the hub after connection loss.
- Up to 1,700 m of secure two-way radio communication in open space
- Encrypted two-way radio communication
- Instant alarm and malfunction notifications
Sabotage resistance
Accelerometer for detecting device movement
Accelerometer detects attempts to detach LifeQuality Lite Jeweller from a surface, remove it from the mounting panel, or move it from a table or shelf. Any such attempt is instantly reported to users and the monitoring company.
Frequency hopping against interference and jamming
LifeQuality Lite Jeweller can detect radio interference and jamming. If transmitted data packets are lost, the device automatically switches to a different frequency within the band and reports the issue to the monitoring company and users.
Device authentication against spoofing
During each communication session, the hub authenticates LifeQuality Lite Jeweller by checking its unique parameters. If any parameter fails the check, the hub ignores the device's commands.
Regular polling to control device state
LifeQuality Lite Jeweller regularly exchanges data with the hub. The system monitors the device state and reports any malfunctions. If the connection between the monitor and the hub is lost, the system detects it in just3 36 seconds and notifies the monitoring company and users of the incident.
Data encryption
The system protects all data transmitted between an Ajax hub and LifeQuality Lite Jeweller using dynamic-key block encryption. This protection makes it extremely difficult to reprogram the device and replace or steal data.
Hassle-free installation and setup
LifeQuality Lite Jeweller is ready to operate straight out of the box, with no wiring or enclosure disassembly required. Device connection, configuration, and monitoring are managed via intuitive Ajax apps — on mobile or desktop.
| Installation | Adding to the system | Setup and monitoring |
| Save time by installing the device with the SmartBracket panel — no enclosure disassembly or wiring required. | Connect the device to the hub by scanning the QR code in Ajax apps. | Adjust thresholds, configure automation scenarios, and view real-time readings and historical data via Ajax mobile or desktop apps. Set up notifications for exceeded thresholds as standard events or as alarms sent to a monitoring station. |
