A zigbee based wearable physiological parameters monitoring system

  1. 1. A Zigbee-Based Wearable Physiological Parameters Monitoring System Abstract The system we are developed to monitor the overall health of welfare facility residents, who need constant care. The wireless technology of electronics is growing day by day. Using this technology, sensor-network arrangement such as distributed and self-organization can be constructed. A portable biomedical system can be build based on the network types available, which can monitor the patient’s health in real time. This system applies Zigbee communication protocol, and uses the RF transceiver. It has the characteristics of low power consumption, low cost, flexible structure and accurate measurement, and it can achieve the long-distance monitoring of patients condition in real time. Existing System: The existing system is based on the wired technology and they actually depend over manual operation. The user’s privacy is not protected in previous wired or wireless sensor network. This proves to be a major drawback in the existing system. Proposed System: This paper presents a system that can be used to monitor physiological parameters, such as temperature and heart rate, of a human subject. Here we are monitoring the patient’s heart beat and body temperature using sensors. The microcontroller uses the algorithm to encrypt the measured data and then it is transmitted using Zigbee wireless communication. The Zigbee in the receiving end is interfaced with a PC; the data received is decrypted and monitored in the PC.
