Poseidon2 4002

Poseidon2 4002 is a remote monitoring system for Server Racks, Server Rooms and Data Centres. It occupies 1U and measures Temperature, Humidity and Voltage and checks for Doors Open, Smoke, Water and more. Relay outputs can activate fans or switch on lights etc. Poseidon2 4002 is SNMP compatible, includes a data logger, e-mail and SMS alerts. It can be connected to the SensDesk online portal or be monitored by PDMS Software.

Additional Product Information

Poseidon2 4002 is a remote environment monitoring system for datacentres and server rooms. It alerts to open door, high temperature and humidity, or other sensor readings. Typical applications include monitoring one or more racks, or the entire server room. Poseidon2 4002 can be mounted on the wall, on a DIN rail, or as a 1U device in a 19” rack.

Use your Poseidon to monitor your computer room temperature via SNMP (Nagios, Cacti, OpenView, ..) or with a smartphone app.

Poseidon2 4002 can be used as a standalone environment monitoring device with email alerts or as a part of a complex monitoring system (SNMP or SensDesk online portal).

Sensors and Detectors

Up to 16 external sensors, 12 detectors with a dry contact output, 4 relay outputs and a GSM modem can be connected. We supply Temperature and Humidity sensors (indoor/outdoor), Light Intensity sensors, DC/AC current and Voltage converters.

Digital Inputs can be connected to Smoke Detectors, Power Failure Sensors, Water Detection Sensors and more. Relay outputs can be controlled over the Web, or according to the value of a connected sensor, eg. Switch on Fans, Lights or Power Down Systems.

E-mail & SMS Alerts

When a value is out of a specified range, Poseidon2 sends an e-mail, a SNMP Trap, or a text message (SMS). Text messages (SMS) can be sent via an external GSM modem, or through a central “HWg-SMS Gateway anywhere on the network. Just a single SIM card can serve all your devices.

Web Interface, Software & Mobile apps

The device can be accessed over the web, using a mobile phone app (Android, iPhone), or through an online portal. Temperature alarms, for example, can be sent by e-mail or SMS.

For data collection and monitoring, we recommend our HWg-PDMS application that displays graphs and exports data to MS Excel.

For “IF-THEN” event management (e.g. “If one out of 10 devices fails, send a SMS to the admin”), we provide the “HWg-Trigger” application for Windows.

For remote monitoring of several sites, the SensDesk.com online service can be used. It can display readings from sensors at multiple Poseidon2 units and other HW group products on a single screen. The online portal is configured over the web and all devices can monitored with a mobile phone app.

Poseidon2 can be connected to various monitoring systems. We support over 50 different third-party SNMP or SCADA applications.

Support for programmers: HWg-SDK

Recommended online portal: SensDesk.com – free online portal

Supported software

HWg-Trigger: Control of other IP devices, alarm redirection to SMS

HWg-PDMS: Logging, export to MS Excel, reports

Third-party software (SCADA systems, Modbus/TCP)
