HW-group Ares12 LTE

Water damage is one of the most serious risks for data centers, server rooms, and technical facilities. Even small leaks can lead to outages, data loss, or high repair costs. With the HWg-Ares12 LTE, HW-group has developed a modern IoT monitoring system that ensures reliable data transmission via LTE connectivity (GSM/GPRS/LTE), even in environments without LAN or Wi-Fi. By connecting up to 14 sensors, not only temperature and humidity can be monitored, but also water leaks can be precisely detected, allowing early intervention.

The device has been specifically designed for critical environments such as data centers, cold storage, industrial facilities, ATMs, or museums. With flexible evaluation options, reliable SMS/e-mail/call alarms, and integration into the SensDesk portal, the Ares12 LTE offers a complete solution for protection against water leakage and water ingress. Support for reusable water sensors makes its operation particularly cost-efficient.

Since the Ares12 LTE operates independently of traditional networks, it is ideal for use in remote or mobile locations. Even in the event of connection interruptions, the integrated data logger (up to 170,000 measurement values) ensures seamless documentation. With FOTA (Firmware-over-the-Air updates via LTE), remote maintenance is efficient and time-saving.

Available in four versions (E plain, E Tset, G plain, G Tset), the Ares12 LTE meets both European and international requirements. Complete kits already include sensors and accessories for immediate commissioning. This makes the device a flexible tool for companies wanting to protect their most vulnerable areas.

Advantages for Leakage Monitoring

• Reliable IoT data transmission via LTE even in remote locations
• Water leak early warning system detecting even the smallest amounts with compatible HWg sensors
• Cost efficiency: reusable water sensors can be cleaned and used again
• Flexibility: ideal for server rooms, warehouses, industrial facilities, and cold chains
• Rapid alerting: SMS, e-mail, and phone notifications to up to 5 recipients
• Seamless integration: compatible with SCADA or monitoring systems via SensDesk, SNMP, and Modbus/TCP

Typical Applications

• Data centers & server rooms: protection against water ingress and HVAC leaks
• Cold storage & warehouses: environmental monitoring including temperature and leakage protection
• ATMs & depots: early warning for water ingress or environmental impact
• Industrial facilities: monitoring of liquid flows and energy usage
• Building technology: precise detection of leaks in basements, archives, and technical rooms

Integration into the Ecosystem

As part of the HW-group monitoring ecosystem, the Ares12 LTE is fully compatible with the SensDesk portal and HWg-Cloud. Users can set custom alarm thresholds, create reports, and analyze sensor data up to two years retrospectively. For large-scale projects, the device provides open interfaces (SNMP, Modbus/TCP, XML) and SDK support – ideal for SCADA systems. Via the relay output module, external devices such as pumps or sirens can also be controlled.

Versions of the Ares12 LTE

• Ares12 LTE E plain: European base version, incl. antenna & USB cable.
• Ares12 LTE E Tset: European complete version with temperature sensor, antenna, power supply, & accessories.
• Ares12 LTE G plain: Global base version for worldwide deployment.
• Ares12 LTE G Tset: Global complete set with temperature sensor, antenna, & power supply.

Can the Ares12 LTE reliably detect water leaks?

Yes, in combination with HW-group water leak sensors, the Ares12 LTE reliably detects liquids and immediately sends alerts via SMS or e-mail.

How many recipients can be notified?

Up to five recipients can be configured to receive notifications via SMS, phone call, or e-mail.

How are firmware updates carried out?

Thanks to FOTA, updates can be conveniently performed remotely via LTE without requiring physical access to the device.
