Measure, log and switch...

The Web-Thermometer is a measuring instrument which detects temperatures and makes the values available in the network. When a limit is exceeded a digital relay output can be switched. The device includes an integrated data logger and numerous Web and network services for manual querying of the measurements, or autonomous sending of messages.
