New product for connecting Pt100 and Pt1000 temperature probes
With Converter 2xPt100 1W-UNI you can measure temperature from two external probes Pt100 or Pt1000.
Double converter to has 1-Wire UNI (RJ11) output. You can connect it with LAN monitoring devices (Poseidon2) or GSM (Ares).
Typical applications include measuring extreme temperatures in furnaces, coolers, engines, etc.
Poseidon2 4002: Data center environment monitoring
Poseidon2 4002 is a system for remote monitoring of rack environmental conditions (occupies 1U). Measures temperature, checks if the lights are on or the doors are open in the server room, and more. Poseidon is SNMP compatible, includes a data logger, e-mail and SMS alerts. It can be connected to the SensDesk online portal or cloud sensor systems.

IP Relay HWg-ER02b
The new IP relay HWg-ER02b replaces the previous model. Adds Modbus/TCP protocol support, WEB config and two DI (Digital Inputs) for external dry contacts.
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:
- Detected water activates a relay: >> HWg-WLD Relay
- Water leak detection connected as a Poseidon sensor:>> HWg-WLD Relay
- E-mail is sent whenever water is detected: >> HWg-WLD
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
