Perseus Monitoring 155 is a sophisticated 1U high environmental monitoring solution for server rooms, data centres, server cabinets, audio visual (AV) installations and other critical application areas that require 24/7 monitoring and automatic alert notifications (store up to 100x email and 100x SMS mobile phone numbers). The Perseus Monitoring 155 unit has a built-in LTE modem that serves as an SMS gateway for Perseus itself as well as other connected HW group devices and provides backup connectivity should there be a local Ethernet outage.

The Perseus Monitoring 155 can connect up to external 8x physical sensors (RJ11 ports) for monitoring temperature (°C), relative humidity (%RH), power Amps and Voltage, for example and up to (16 DI/4 DO) dry contact detectors including water leak detectors (WLD) and sensing cables and 3rd party meters. Sensors can also be connected via LAN or Modbus/RTU.

PERSEUS 155-RACK-TSET	Perseus 155 Rack Kit containing 1x Perseus Monitoring 155, 1x set of RM2 19inch brackets, a universal power adaptor 12V 1.5A, 1x water leakage WLD sensing cable A 2+2m, 1x Temp-1Wire Rack19 temperature sensor, and 1x Door Contact MK4 set

Perseus 155 combines data from external physical sensors and detectors with data from other HWg Group devices connected via LAN. Local conditions, Lua scripting, calendar or periodic scheduler for analysis and trend reporting. Email or SNMP Trap alerts can be automatically sent from the Perseus Monitoring 155 device. Measured values are also available via Open API (XML, Modbus/TCP, MQTT). Perseus can be connected to the Cloud based SensDesk portal for remote site and multiple device monitoring. A unique feature of all Perseus products is the Meters Open API. This means that Perseus system can read over LAN sensor values from other devices (for example the STE2-R2) and use this data for analysis or automatic alert notifications.

Monitoring Portals and Mobile App

HW Group provide two portal options.

The free HWg Cloud monitoring portal features:

Automatic email alerts can be sent when an alarm condition occurs
Device Invalid (disconnected) alert is available to provide a heartbeat/watchdog function
A single value graph with short historical data
Alarm escalation (email only)
Remote relay output switching based on sensor values
Central alerts overview and device management

The SensDesk Technology portal (SaaS or On-Premise) has an annual license and provides more extensive features including:

Email, SMS, Voice call alerts
Multigraphs with several years of history
User account API: SNMP or XML
Reports (PDF)
Multi-user accounts

Perseus 15 can also be monitored using HWg Monitor, a mobile phone App available for Android and iOS mobiles and tablets.
