Monitor, archive and display temperature, relative humidity and air pressure

Web Thermometers are measuring devices which depending on the type detect temperatures, relative humidity and barometric pressure and provide the values to the network. The devices include an integrated data logger and numerous Web and network services for manually querying the measurement values or for independently sending messages.

  • Web Thermometer

Simplified integration procedure for W&T devices with network connection

  • 1. Attach temperature or combi-sensor.
    Step 1
  • 2. Connect device to the network.
    Step 2
  • 3. Connect power supply.
    (Alternatively PoE may also be used for power)
    Step 3
  • 4. Assign IP address.
    (Now made even easier by our management tool WuTility)
    Step 4
  • 5. That’s it!

    Read out:

    • directly from the Web browser interface,
    • in your own application via TCP/IP socket/UDP query,
    • in management systems (SNMP, OPC),

    and send alarms via e-mail and SNMP trap.
