HW-group Perseus Monitoring 140

Water damage caused by unnoticed leaks is among the most frequent and severe problems in data centers, server rooms, and industrial facilities. Even a few drops can damage expensive hardware, disrupt processes, and cause costly consequences. The HW-group Perseus Monitoring 140 is a comprehensive LAN-based monitoring system designed to provide reliable protection against water leakage and ingress. In addition to monitoring temperature, humidity, voltage, and current, the device specifically detects water leaks – serving as a versatile early warning system for critical infrastructures.

The Perseus Monitoring 140 supports a wide range of sensors via 4x RJ11 ports for 1-Wire UNI sensors, RS-485 Modbus/RTU, and a dedicated WLD input for water detection cables up to 185 m in length. This creates a flexible system suitable for environments ranging from data centers to industrial halls to pharmaceutical storage facilities – providing reliable leak detection.

With support for up to 1000 monitored variables, its own web interface, and SCADA/IoT integration via SNMPv3, Modbus/TCP, MQTT, or XML, the system is ideal for modern enterprises demanding maximum safety and prevention standards.

Key Features

• WLD input: direct connection for water leak detection cables (up to 185 m).
• Sensor diversity: monitoring temperature, humidity, voltage, current, CO₂, and more.
• Digital I/O: 4 digital dry contact inputs (e.g., door sensors, smoke detectors) and 2 digital outputs for relay control.
• Modbus/RTU: RS-485 port for energy measurements and industrial Modbus sensors.
• Data processing: Lua scripting, scheduling, and aggregation through virtual sensors.
• Data logger: event storage with analysis via HWg-PDMS and export to Excel.
• Alarms: via e-mail, SNMP trap, or SMS/voice with an external SMS gateway.
• Meters API: unique ability to aggregate data from other LAN devices (e.g., STE2 R2, UPS) into its own analysis.
• Security: HTTPS, Radius (IEEE 802.1X), admin/user accounts, IPv6, SNMP v3.

Water Leakage Protection

The Perseus Monitoring 140 is optimized for water ingress protection. Using a WLD sensor cable, raised floors in server rooms, pipelines in technical areas, or cooling units can be monitored. When conductive liquid is detected, the device immediately sends a warning – by e-mail, SNMP, or optionally SMS. This ensures that damages are avoided before critical failures occur.

Typical Applications

• Data centers & server rooms: monitoring of temperature, humidity, and water leaks under raised floors or AC units.
• Warehouses & cold storage: controlling cooling areas with combined temperature and water leak detection.
• Pharma & food industry: HACCP-compliant monitoring including liquid detection.
• Telecom sites: protecting sensitive facilities by monitoring water leaks and power supply.
• Building management: use as a central system for climate, access, and water leak monitoring.

Software Integration

Integration into the SensDesk portal or HWg-cloud.com allows centralized alarm escalation, PDF reports, graphs, and multi-user management. The device supports open protocols, enabling easy integration into SCADA systems. Developers can create custom applications using APIs (SNMP, Modbus/TCP, MQTT, XML).

Mobile Monitoring

With the HWg Monitor app (iOS/Android), users maintain mobile access to their sensor data at all times. Water leak or environmental alarms appear instantly on smartphones. Widgets allow critical parameters to be displayed directly on the home screen for rapid detection.

Versions

• Perseus Monitoring 140: base model for custom configuration, without power adapter or sensors.
• Perseus Monitoring 140 TSet: starter kit including 3 m IP67 temperature sensor and power adapter for immediate use.

Can the Perseus Monitoring 140 reliably detect water leaks?

Yes, a water leak detection cable (up to 185 m) can be connected via the dedicated WLD input. This enables the system to detect even the smallest amounts of liquid.

How are alarms triggered in case of water ingress?

The device alerts via e-mail, SNMP trap, or HWg-Push. With an external SMS gateway, additional SMS and voice call notifications are possible. Through SensDesk portals, alarms can be escalated and detailed reports generated.

For which environments is the Perseus 140 suitable?

The device is suitable for server rooms, industrial warehouses, technical facilities, pharmaceutical and food environments, as well as smart building monitoring. It is especially valuable in areas where water damage could have severe consequences.
