Ajax LifeQuality Lite

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.

Temperature measurement

Sensitive element: digital temperature and humidity sensor
Values in Ajax apps are updated at least once per minute.

Measurement range: from −30 °C to +50 °C

Measurement accuracy:
±0.2 °C (from 0 °C to +50 °C)
±0.3 °C (from −10 °C to 0 °C)
±0.4 °C (from −20 °C to −10 °C)
±0.5 °C (from −30 °C to −20 °C)

Measurement pitch: 0.1 °C

Humidity measurement

Sensitive element: digital temperature and humidity sensor

Measurement range: from 0% to 100%

Measurement accuracy: ±1.8% (when the temperature is above 0 °C)

Measurement pitch: 1%

Additional features

• Charts of temperature and humidity — available in Ajax apps, data stored for up to two years.
• LED indication: green (acceptable level), yellow (beyond acceptable levels).
• Scenarios: responses to changes in temperature or humidity (e.g., enabling plenum ventilation).
• Backup memory: up to 3 days — stores all measured values if communication with the hub is lost.

Recommendations

The device is designed only for indoor installation at any height. After exposure to low temperatures, keep at room temperature for 8–12 hours to prevent condensation. The device can be placed on a table or shelf.

Sabotage protection

Protection against spoofing — device authentication.
