HW-group Perseus Energy 240

Undetected water leaks are among the biggest risks for server rooms, data centers, and industrial facilities. The HW-group Perseus Energy 240 is a compact yet powerful system that not only acts as a Modbus gateway but can also be flexibly used for monitoring water leaks and water ingress. The device connects RS-485 sensors via Modbus/RTU to modern networks through Modbus/TCP, MQTT, or SNMP – enabling seamless integration into IoT and SCADA platforms.

Supporting up to 100 sensors and more than 1000 variables, the Perseus Energy 240 provides a flexible foundation for water leakage detection as well as general monitoring of critical environmental conditions such as temperature, humidity, current, or voltage. This makes it an excellent choice for companies that need to protect sensitive infrastructure with a cost-efficient solution.

Powerful Monitoring Functions

• RS-485 integration: connect up to 100 Modbus/RTU sensors, including water leakage detectors
• LAN connectivity: conversion of Modbus/RTU to Modbus/TCP, MQTT, or SNMP for network integration
• Meters API: unique ability to pull data from other LAN devices (e.g., STE2 R2, SNMP UPS)
• Data logger & analysis: support for Lua scripting, scheduling, and virtual sensors for aggregation
• Secure communication: HTTPS, Radius (IEEE 802.1X), IPv6, and SNMP v3 ensure protection and security
• Leak detection alarms: instant notification via e-mail, SNMP trap, or external SMS gateway

Protection Against Water Leakage and Ingress

The Perseus Energy 240 enables integration of RS-485–based water sensors into network environments, actively helping to detect water ingress early. Typical applications include monitoring pipelines, AC condensation, or raised floors in server rooms. When liquid is detected, the system immediately sends an alarm – via e-mail, SNMP trap, or through an SMS gateway such as the HWg-SMS-GW3. This enables rapid response before damage occurs.

Typical Applications

• Data centers & server rooms: integration of RS-485 leak sensors to monitor raised floors, HVAC, and power systems
• Building technology: protection of technical rooms against flooding or pipe failures
• Pharma & food storage: precise monitoring including water protection for HACCP-compliant reporting
• Telecom sites: supervision of humidity-sensitive equipment to ensure operational stability
• Industrial facilities: integration of process sensors for fluid or energy monitoring

Integration & Software Support

Integration with SensDesk portals greatly enhances features – from graphical dashboards and alarm escalation to PDF reports for audits. While HWg-cloud.com offers basic functionality free of charge, SensDesk SaaS or On-Premise provides SMS/voice call alarms, multi-user support, and API integration. Developers also benefit from the open API (SNMP, Modbus/TCP, MQTT, XML), enabling easy connection to SCADA or complex IoT environments.

Mobile Monitoring App

With the free HWg Monitor App (iOS/Android), users maintain mobile access to all monitored data anytime. Water leakage alarms and other parameters can be checked instantly, even off-site.

Versions

• Perseus Energy 240: base version without power adapter, ideal for custom installations
• Perseus Energy 240 Set: includes power adapter, fully equipped for immediate deployment

Can the Perseus Energy 240 detect water leaks?

Yes, by integrating RS-485–based water sensors, the device enables reliable detection and alarm notifications when liquid is detected.

How are alarms delivered?

The device sends alerts via e-mail, SNMP trap, or optionally through SMS/voice calls using an external SMS gateway. Additional alarm escalation can be configured through the SensDesk portal.

Is the Perseus Energy 240 suitable for SCADA environments?

Yes, thanks to Modbus/TCP, MQTT, SNMP, and XML support, the Perseus Energy 240 is fully integrable into SCADA and IoT platforms.
