Biometric sensor array

The Biometric Sensor Array is a console found in Atlantis that was moved to Stargate Operations by the Atlantis expedition in their first year. The console activates the internal (and external) sensors and is able to locate and differentiate between life forms. The console was activated after being touched by Chaya Sar (who was an Ancient) which led Dr. McKay to believe she was not who she claimed to be ATL|Sanctuary}}. Later that year the device was used to locate a [[Wraith hiding in the city.
