Temperature monitoring in refrigerators and cooling boxes

07. 04. 2011

A Poseidon 2250 unit monitors storage conditions for food or pharmaceuticals. Up to 30 probes can be connected – temperature, humidity, air pressure, door contacts.

• Values are logged in the internal memory.
• Temperature probes use a thin, flat cable that can lead through the door sealing. No need to drill a hole into the refrigerator or worry about batteries.
• Alerts by e-mail or SMS (text message) if the refrigerator door is not fully closed.
• Connects to SNMP monitoring systems.
• Readings can be processed with the supplied HWg-PDMS software (Windows) or with third party software.
• A GSM modem can be connected in order to alert the responsible person to electricity outages by text messages (SMS).

Damocles MINI - SNMP Web relay

01. 04. 2011

Damocles MINI is Web-relay with 4 digital inputs and control 2 NO/NC relay outputs over the Web and M2M (SNMP, XML, Modbus/TCP). Dry contact event email or SNMP Trap alert.

Control two remote relays and four digital inputs (dry contacts) with a Web interface. Switch a relay or check the input states over an IP network.

The Damocles MINI is a SNMP / WEB relay that is typically used to remotely switch On/Off other devices or to measure energy consumption (using pulse counters at the inputs).
When an input contact is closed, Damocles sends an email with customized text. Optionally, the email can be sent after a defined delay (for example, to send an alert if a freezer door stays open for more than 5 minutes).

A typical application is the sending of an email based on Dry contact inputs, remote restart or remote relay control. Relay outputs can be controlled over M2M protocols SNMP, XML over http or Modbus/TCP.

• 4 DI digital inputs for contact connecting
• 2 DO relay outputs relay contacts (NC and NO)
• Sensor value out of range: sending Email or SNMP Trap to several recipients.

Damocles 1208: Remote electricity consumption metering

22. 06. 2010

Damocles 1208 is a cost-effective Ethernet-enabled device with digital inputs (12) and relay outputs (8) accessible over a LAN. Typical applications involve counting pulses from electricity meters, water meters, gas meters etc. User interaction is simplified by the HWg-PDMS application for Windows that counts the pulses, calculates consumption and creates outputs for statistical processing in MS Excel.

Damocles 1208 is a device with general-purpose inputs and outputs. Outputs can be controlled over the Web as well as using M2M protocols for IT (SNMP) or industrial SCADA systems (Modbus/TCP).

Counters at digital (dry contact) inputs allow remote energy (or flow) metering by counting pulses from energy meters. Users can process the data using the free HWg-PDMS utility for Windows. HWg-PDMS can convert pulses to kWh/s (l/s, m3/s) and create MS Excel reports. The protocol then gives a concise overview of kWh consumed per week / month for each electricity meter.

HWg-WLD: Water leak detector

14. 06. 2010

HWg-WLD is a network-enabled water leak detector with a water-absorbing sensing cable. HWg-WLD features a built-in web server, SNMP support, and e-mail alert to water flooding. HWg-WLD can remotely control a relay output over the network (a relay is switched when a water leak is detected along the sensing cable).

• Ethernet: RJ45 (100BASE-T)
• WEB: Built-in web server
• Water flood detector: 2 m (6.5 ft) leader cable + 0.4 m (1.3 ft) sensing cable The sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid

1. The detection cable is reusable
2. The detection cable can be supplied in custom lengths

• Remote output: When a water leak is detected, a remote relay is activated over the network (any Poseidon / Damocles)
• M2M communication protocols: SNMP, XML, Box-2-Box
• Power:

1. Power adapter
2. PoE (IEEE 802.3af) + power adapter (depending on type)

Data cabinet monitoring over GSM and LAN (SNMP, E-mail, SMS)

12. 02. 2010

Independent rack monitoring over IP and GSM. Open door, high temperature or electricity outage is signaled by SMS to several phone numbers. E-mail and SNMP trap are also sent. It is possible to connect a horn (local alarm) or a fan (local cooling). The solution is designed for 19” cabinets.

• Whenever the cabinet (19” rack) door is opened, you receive a SMS and an e-mail
• A text message (SMS) or a SNMP trap alert you to high temperature, or to electricity outage
• GSM monitoring does not depend on LAN functionality

Dangerous situations

• Unauthorized access to a cabinet
• LAN connection failure
• Cabinet door accidentally left open, overheating
• Electricity outage – remote restart

Advantages

• SMS alerts independent of LAN, Poseidon sends a SMS to two phone numbers
• Monitoring of electricity outages, temperature problems and cabinet access over E-mail, SMS and SNMP
• Ability to restart the equipment remotely
• Control unit and probes are designed for 19” rack mount
• Cabinet access monitoring (log)

SMS and SNMP monitoring of temperature / humidity

10. 01. 2010

Temperature and humidity is monitored with a web thermometer that is also capable of sending alerts as text messages (SMS). High temperature alerts are sent by E-mail / SNMP trap as well as by SMS (via a GSM modem).

Poseidon 4002: Rack mount environment monitoring

24. 12. 2009

The Poseidon 4002 is a 19" 1U rack mount system for datacenter temperature and environment monitoring. The Poseidon presents the solution for monitoring of the racks and computer rooms (temperature, humidity, electricity supply, access to the room, detectors). The device alerts by e-mail, SNMP traps, SMS, output relays

The Poseidon 4002 is a complete system for environment monitoring in a 19\" rack, an entire server room or in a datacenter. The 4002 model can be mounted as a 1U device, or outside of the 42U space. 18 sensors are supported (temperature, humidity, smoke, flood, electricity supply status or failure, entry to the room, digital inputs).

The device is SNMP compatible. Two monitoring applications (PD Trigger and HWg-PDMS) are included free of charge.
