PerseusMonitoring 150

Perseus Monitoring 150 is a complex 1U solution for a 19“ rack monitoring system in data centers, AV installations, telecommunications, etc.

Typical applications

• Data Center / Single rack monitoring

• Remote technical room monitoring

• Telecommunication installations

• Remote infrastructure

Perseus 150 combines data from external physical sensors / detectors with data from other HWg devices connected via LAN. Local conditions, Lua scripting, calendar or periodic scheduler help to analyze the measured data.

Email or SNMP Trap alert can be sent from the Perseus device. Measured values are available via Open API (XML, Modbus-TCP, MQTT).

Perseus Monitoring 150 can be connected to the Portal (SensDesk technology). Together with the Portal it’s a powerful solution for professional applications.

A unique feature of Perseus products is the Meters Open API. This means that Perseus can read over LAN sensor values from other devices (e.g. STE2 R2) and use this data for analysis or alerting.


  • Ethernet: RJ45 (100BASE-T); WEB: Built-in web server

  • Sensors: 8xRJ11 port - max. 100 external sensors (1-Wire / 1-Wire UNI) RJ11 sensors: Temperature, Relative Humidity (Indoor / Outdoor), Voltage, Current (0-30A or 4-20mA) and much more…

  • RS-485 (Modbus-RTU): 1x terminal block (With 12V)

  • WLD: 1 zone for external Water Leak Detection sensing cable

  • DO (Digital Outputs): 4x DO (relays)

  • DI (Digital Inputs): 16x DI (dry contact). Detectors: Smoke, door contact, fan failure detector, power presence

  • Alerts: SNMP trap, email, (SMS / Calls with external SMS GW)

  • Open API: SNMP, XML, Modbus/TCP, MQTT

  • Professional product: IPv6, SNMP Traps, SNMP v3

  • Security: Radius - IEEE 802.1X, Admin and user accounts, HTTPs (customer certificate)

Perseus Monitoring 150 is a 19" rack mount device for environmental monitoring of a data center cabinet or entire server room. Up to 100 external meters (sensors) with 1000 values (variables) can be connected.

Within one 19” rack unit there are useful 8 RJ11 ports for external 1W-UNI sensors, 16 DI ports (dry contacts), 1 WLD zone input for Water Leak Detection sensing cable, and 4 relay outputs. Perseus 150 can be powered from 12V, -48V or from PoE.

The combination of the RS-485 physical interface on the Perseus 150 and the Modbus-RTU Meters Open API allows data to be read from third party electricity meters, UPS or air conditioning products.

Perseus Monitoring 150 has a WLD zone input and 4 relay outputs that can be controlled via the device’s interface or according to the value of a connected sensor or detector, for example to control air conditioning, ventilation or automatic doors.

Using Portal service (

  • Email alert can be sent from the Portal (higher long-term reliability)

  • Device Invalid (disconnected) alert is available from the Portal

  • One value graph with short history is available

  • Alarm escalation is available (email only)

  • Remote relay output switching based on sensor 

  • Central alerts overview & management.

  • Free of charge service from HW manufacturer.

Using paid Portal service (Portal providers):

  • SensDesk Technology portal (SaaS or On-Premise)

  • Email, SMS, Voice call alerts

  • Multigraphs with several years of history

  • User account API: SNMP or XML

  • Reports (PDF)

  • Multi-user accounts

Mobile App: HWg Monitor

  • Data input: LAN devices / Portal user account

  • Android and iOS versions.

  • All sensor values on one screen.

  • Can be used as sensor values display on the wall.
