In cold rooms, underground warehouses and other temperature-sensitive areas, the Ajax LifeQuality Lite Jeweller can continuously monitor environmental conditions and record changes over time. Its operating range down to -30 °C makes it particularly suitable for installations exposed to low temperatures. Ajax notes that wireless communication range may be significantly reduced when the device is installed inside commercial freezers, so signal strength should be checked during commissioning.
In greenhouses, laboratories or office environments, installers can define permitted temperature and humidity thresholds within the Ajax system. If these values are exceeded, automation scenarios can activate compatible relays or smart devices to control heating, air conditioning, extraction systems or humidifiers. This allows the LifeQuality Lite Jeweller to form part of an automatic environmental control solution rather than acting only as a monitoring sensor.
