Abstract: The system comprises one or more sensor devices, where each sensor device is capable of measuring a temperature at a known location of a body of a human or other animal. Each sensor transmits a temperature measurement value and sensor identification to a monitor device. The monitor device receives the temperature measurement value and sensor identification, and computes an adjusted temperature value based upon the position of the measuring sensor, body age, and time of day. The adjusted temperature value is tested for alarm conditions and displayed for use by a caretaker.
