Measure, log and report...

The Web Thermo-Hygrometer XT is a measuring device that records temperatures and humidity in harsh environments and makes the values ​​available in the network. The device has an integrated data logger and numerous web and network services for manually querying the measured values ​​or automatically sending messages. The measuring device has protection class IP67, the sensor IPX4. This means that the device can be used in harsh environments.
