HW-group Perseus Monitoring 145

The HW-group Perseus Monitoring 145 is a LAN-based monitoring system with integrated LTE backup, ensuring uninterrupted supervision and alerting even if the primary network connection fails. This dual connectivity makes it ideal for mission-critical infrastructures in data centers, telecom sites, industry, and building management.

Supporting up to 1000 monitored variables, the Perseus 145 integrates a wide range of sensors. With 4 RJ11 ports for 1-Wire UNI sensors, one RS-485 Modbus/RTU port, 4 digital inputs (DI) for dry contacts, and 2 digital outputs (DO) for external relay control, it covers multiple applications such as temperature, humidity, energy monitoring, access control, and facility automation.

Technical Highlights

• Dual connectivity: LAN + integrated LTE module
• 4 × RJ11 ports for up to 8 sensors; RS-485 Modbus/RTU support
• 4 digital inputs (DI) and 2 digital outputs (DO)
• Alerts via email, SNMP trap, SMS, or voice calls over LTE
• Data logic with Lua scripting, schedules, and virtual sensors
• Open APIs: SNMP, Modbus/TCP, MQTT, XML
• Datalogging with export via HWg-PDMS to MS Excel
• Secure comms: SNMPv3, HTTPS, Radius (802.1X), IPv6 support

Data Processing & Automation

More than monitoring, the Perseus 145 supports Lua scripting, virtual sensors, and schedules for tailored automation. Relays enable direct activation of fans, HVAC systems, or security devices, supporting advanced facility automation workflows.

Alerts & Fail-Safe Operation

Alerts are issued instantly via email, SNMP traps, or SMS/voice using the LTE backup link. Even during LAN outages, alarm delivery remains active, ensuring robust reliability for critical sites.

IoT & SCADA Integration

Supporting SNMPv3, Modbus/TCP, MQTT, and XML, the Perseus 145 integrates with SCADA and IoT platforms. The Meters API aggregates data from LAN devices (e.g. STE2 R2, UPS) to form a scalable central monitoring platform. With SensDesk SaaS or on-premise deployment, companies gain centralized dashboards, PDF reports, alarm escalations, and multi-user access.

Data Logging & Analysis

An integrated datalogger stores key metrics for long-term use. Data can be analyzed with HWg-PDMS software and exported to Excel for reporting, compliance, and trend recognition.

Mobile Monitoring

Through the HWg Monitor app (iOS/Android), admins access live data anywhere. Smartphone widgets display critical parameter states instantly for full mobility.

Application Areas

• Data centers & server rooms – temperature, humidity, power, door contacts
• Telecom – continuous monitoring with LTE redundancy
• Pharma & food – HACCP-compliant monitoring of environmental conditions
• Industry – power, voltage and machine parameter tracking
• Building management – access systems, smoke detectors, HVAC integration

Variants

• Perseus Monitoring 145: Base unit with LAN & LTE, no PSU or SIM card
• Perseus Monitoring 145 TSet: Starter kit with PSU, LTE antenna, and sensor

Conclusion

The HW-group Perseus Monitoring 145 combines LAN and LTE redundancy in a powerful monitoring platform. With extensive sensor support, Lua scripting, cloud integration, and advanced alerting, it ensures maximum reliability for IT, industry, building, and telecom operations. Flexible, scalable, and future-proof, it delivers continuous monitoring with unmatched resilience.
