Abstract: A device for detecting infrared radiation emanating from a subject while not in physical contact with the subject. The device includes a body, an infrared sensor located in the body oriented to receive the infrared radiation and to generate at least one output that corresponds to the received infrared radiation, an analog to digital converter in communication with the infrared sensor to receive the at least one output, a processor in communication with the analog to digital converter or infrared sensor to process data received into a temperature associated with the subject, a memory module to store a first plurality of computed temperatures in a predetermined sequence; and a filter module to select a first maximum from among the first plurality of computed temperatures. A method of determining the temperature of a subject is also provided.
