ABSTRACT: A ZigBee sensor network for data acquisition and monitoring is presented in this paper. A ZigBee module is connected via a USB interface to a Microsoft Windows PC, which works as a base station in the network. Data collected by sensor devices are sent to the base station PC, which is set as Wireless sensorNetwork (WSN). ZigBee is low power consumption, built-in security method and ratified specifications make it very suitable to be used with medical sensor devices.This application of Zigbee based network consists of two transmitter sections and a receiver section.Each transmitter section consists of heartbeat sensor, body temperature sensor, microcontroller, Zigbee and LCD module.In the proposed system the patient’s health is continuously monitored and theacquired data is analyzed at a personal computer using Graphical User Interface(GUI). If a particular patient’s health parameter is higher or lower the threshold values, an alarm system is used to alert the doctor. The aim of this system is to know the condition of patient’s health by the doctor immediately and to reduce the load of the staff taking care of the patient in the hospitals. In this paper, wireless point to multipoint system is used between doctor and patient.
