  This paper addresses the design and implementation of a real time temperature
monitoring system with applications in telemedicine. The system consists of a
number of precision wireless thermometers which are conceived and realized to
measure the patients body temperature in hospitals and the intensive care
units. Each wireless thermometer incorporates an accurate semiconductor
temperature sensor, a transceiver operating at 2.4 GHz and a microcontroller
that controls the thermometer functionalities. An array of two thermometers are
implemented and successfully evaluated in different scenarios, including free
space and in vivo tests. Also, an in house developed computer software is used
in order to visualize the measurements in addition to detecting rapid increase
and alerting high body temperature. The agreement between the experimental data
and reference temperature values is significant.
