HW-group Perseus Monitoring 150 – Reliable protection against water leakage and water ingress in data centres
HW-group Perseus Monitoring 150
In critical environments such as data centers, telecom facilities, and server rooms, unnoticed water leaks pose one of the greatest risks. Even a few drops can cause short circuits, system failures, and massive costs. The HW-group Perseus Monitoring 150 provides an advanced solution for precise water leakage detection along with comprehensive environmental monitoring – specifically designed for professional 19” rack environments.
The device monitors up to 100 sensors (1000 variables), including key parameters such as temperature, humidity, current, voltage, and smoke detection. For water ingress protection, a dedicated WLD input supports up to 185 m of water detection cable, ensuring instant leak alarms that prevent costly damages.
With 8 RJ11 ports for 1-Wire UNI sensors, one RS-485 Modbus/RTU port, 16 digital inputs, and 4 digital outputs, the Perseus Monitoring 150 integrates extensive functionalities. Door contacts, smoke, or motion sensors can be connected, while relay outputs enable immediate countermeasures, such as activating pumps or sirens.
Integration into IoT and SCADA environments is seamless thanks to open protocols (SNMP, Modbus/TCP, MQTT, XML) and the Meters API, which aggregates LAN device data (e.g., from STE2 R2 or UPS). SensDesk portals add PDF reporting, alarm escalations, and mobile analytics.

Protection Against Water Leakage and Ingress
The WLD functionality makes the Perseus Monitoring 150 particularly valuable for data center operations. Detection cables can monitor raised floors, air conditioning areas, or pipelines. Once conductive liquid is detected, alarms are sent instantly by e-mail, SNMP, or SMS gateway to technicians. Reusable sensor cables ensure long-term cost efficiency.
Typical Applications
- Data centers & server rooms: full protection against leaks, overheating, and risks
- Telecom facilities: safeguarding sensitive technical rooms against moisture and power problems
- Pharmaceutical & food storage: HACCP-compliant monitoring with leakage detection
- Smart buildings: integration into facility management for climate and water protection
- Individual racks: precise rack temperature and leakage detection for high-density setups
Integration & Software
Professional integration is ensured via open interfaces. With SNMP v3 and HTTPS, high-level security standards are met. SensDesk portals provide centralized alarm dashboards, PDF reports, and multi-user management. Developers benefit from the Meters API, which aggregates external device data for even more precise insights.
Mobile Monitoring
With the HWg Monitor App (iOS/Android), administrators are always informed – whether via LAN, HWg-Cloud, or SensDesk. Leak alarms appear instantly on smartphones, enabling immediate reaction.
Versions
- Perseus Monitoring 150: base model for custom configuration, without power supply or mounting kit

Summary
Does the Perseus Monitoring 150 support water leakage detection?
Yes, water detection cables (up to 185 m) can be connected via the dedicated WLD port. Even small amounts of liquid immediately trigger alarms.
How are alarms triggered in case of water ingress?
The device sends alarms via e-mail, SNMP trap, and push signals. With an external SMS gateway, SMS or voice call notifications are also possible. Through SensDesk portals, escalations and detailed reports can be configured.
For which environments is the system suitable?
The Perseus 150 is ideal for large data centers, industrial control rooms, and any environment where water leakage could have severe impacts on infrastructure.
