Overview

All Sensatronics EM1 Environmental Monitors come with a built-in webserver. This means that you can view the current readings simply by entering the IP address of the Monitor in your browser. The Index page appears showing details of the Monitor and readings from the various probes attached to the Base Unit.

By default the temperature readings are shown in degrees Fahrenheit, but this can be changed to read in Celsius, Kelvin, or Rankine.
