Web-Thermo-Hygrobarometer

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.
