Wireless embedded device (PIC) based on MiWi technology for monitoring physiological parameters

Patient monitoring system are gaining importance due to the emergence of cardiac diseases which demands for monitoring of health status of patient. Therefore a system has been developed to monitor physiological parameters such as temperature, ECG, heart rate of patient. To detect distress condition a fall detection sensor has been incorporated. Theses parameters are acquired and processed using PIC16F877A microcontroller and are sent wirelessly using Microchip Proprietary wireless protocol to the receiver unit which is connected to the computer. The computer has monitoring software which displays these parameters. The device also detects medical distressed conditions by comparing with threshold values and sets off alarm and sms alert to the hospital or caretaker. This device can improve the functional effectiveness of the medical care taking by attending the problems in time which saves many lives.
