In order to monitor the variation of body temperature from multi-patient in real-time in the hospital room, a miniaturized wireless telemetry module based on PAN was designed and implemented in this paper. The transmitting part of telemetry system consists of a temperature sensor, a miniaturized UHF transmitter with a transmitting antenna, a microprocessor for data encoding, and a battery. The diameter and thickness of implemented transmitter are 20 mm and 3 mm respectively. The receiving part consists of a receiving antenna, a RF receiver, and a processor for data decoding, and the decoded data was transformed to RS232C format to be transferred to computer. From the experimental result in the simulation environment that resembles a hospital room, the implemented telemetry module was verified to operate well with sufficient reliability.
