HW group produces IP-enabled sensors

HW group s.r.o. is a manufacturer of sensors with IP interface. We provide solutions for remote monitoring and remote control over M2M. Our products are designed for IT SOHO, datacenters, industrial and security applications. More about us

Applications of our products:






Temperature monitoring over Web, SNMP, e-mail

The HWg-STE IP Thermometer enables remote temperature monitoring over a LAN. If the system overheats or a temperature is exceeded, an e-mail alert is sent. Supplied with the HWg-PDMS software for Windows – charts, export to MS Excel.

  • E-mail alerts to faulty air conditioning
  • Alerts to equipment overheating (server, disk array)
  • Alerts to rising temperature in a room
  • Quick and easy installation (DHCP supported)
  • Connects to SNMP monitoring systems
  • Free HWg-PDMS software for Windows (MS Excel exports)

Temperature monitoring in refrigerators and cooling boxes

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).

Poseidon 4002 – Rack Monitoring System

A Poseidon 4002 unit with various sensors and probes (temperature, humidity, door contacts, power supply, water flood) monitors the environment inside a 19" cabinet.

It can report over SNMP to any datacenter or IT monitoring system.

  • Two different people can be alerted by SMS (text message) to an electricity outage or phase loss
  • You immediately know when someone opens the cabinet (SNMP Trap, pop-up window)
  • E-mail alerts you in time to rising temperature
  • You can check the cabinet status remotely over the Web
  • You can remotely restart a server or switch on air conditioning

Water flood detection

Water or any other conductive liquid is detected along the entire length of the WLD sensing cable.
The WLD sensing cable can be extended with a regular cable. This allows for optimizing the costs for a detection zone.

Examples of use:
  • Water detection under raised floors
  • Leaky pipe detection (cable routed along the pipe)
  • Detection of liquids in drip trays
  • Water leak from air conditioning units

Flood detection outputs:


 

Electricity consumption metering

HWg-PWR collects data from meters over M-Bus (data are logged into the internal memory). Consumption charts can be plotted over the Web, e-mail alerts to overcurrent can be configured.
HWg-PWR can send detailed billing information every month. With a certified M-Bus electricity meter, costs can be directly invoiced, or cos Phi monitored.

M-Bus meters are not limited to electricity meters. M-Bus heat meters, gas meters or water meters can be also connected. HWg-PWR is an intelligent gateway for connecting any M-Bus meter to your LAN.

Box-2-Box: Relay control over LAN

Two I/O Controller units can be connected against each other over a LAN. Digital inputs are then connected over the network to relay outputs. The delay is approximately 200ms. With a remote LAN relay, it is possible to switch any device on or off.


  • Each unit can connect to the remote unit
  • When the power fails and is restored, the unit automatically retrieves input states from the remote unit
  • Uses a Telnet-like protocol with optional security enhancements
