A lot of research has been carried out in the field of health care monitoring. In the recent years, development of wireless health care monitoring system has emerged as an area of research. The presented work falls under the health care monitoring system. Here the system monitors the patient continuously while simultaneously transmitting the physiological data to the doctors and other medical staff. The presented system is based on a dedicated communication protocol for sensor networks, ZigBee. The system has low cost, low power requirements and compact. The performance of the system is analysed for indoor and outdoor environment, under various conditions. It is observed that the system provides reliable monitoring and secure wireless transmission of the monitored data. Further it is observed that the current consumption of the system is 64.1 mA and 71.2 mA at the sensing node and coordinator respectively, when transmitted power is set at -18 dBm. The range of the system varies from 10m (indoor environment) to 30m (line of sight range in outdoor environment) at -18 dBm transmitted power, which is suitable for hospital environment.
