Vertiv Geist Remote Sensor - Temperature, Humidity and Dew Point, 2 x RJ12 Ports

The GTHD digital sensor collects and transmits real-time temperature, humidity and dew point data to protect critical data center equipment from heat and moisture. The GTHD model offers two RJ12 ports, one uplink port to connect to a host device and a supplementary input for daisy-chaining.

The GTHD requires a host device to transmit data. It counts as a single digital sensor while reporting multiple temperature readings. The unit may be daisy chained with other GTHD or GT3HD sensors to form a sophisticated climate monitoring network with real-time data logging and alarming. This is especially useful when achieving in-row temperature monitoring for top, middle, and bottom of each rack as per ASHRAE guidelines. (Figure 1) The plastic enclosure mounts easily anywhere in the data  center with screws, magnets or adhesive.
