Environmental measuring apparatus

摘要

An environmental measuring apparatus for measuring a plurality of environmental conditions within a server rack or a server room may include a plurality of sensing devices for detecting the plurality of environmental conditions, and a measuring device electrically connected to the sensing devices and having a plurality of predetermined voltage-physical value converting tables previously stored therein. Each of the sensing devices is arranged and constructed to generate at least one analog sensing voltage representative of a detecting value corresponding to the environmental condition and at least one sensing device identification signal corresponding to the sensing device. The measuring device is arranged and constructed to select a corresponding voltage-physical value converting table from the voltage-physical value converting tables based on the at least one sensing device identification signal and to convert the at least one analog sensing voltage to a physical value with reference to the selected voltage-physical value converting table.
