Patient Monitoring System Using Wireless Sensor Network

The main objective of this project is to improve the patient monitoring system and to enhance portability of health records. This is achieved by collecting a patient’s parameter using a controller and transmitting it to a computer through a wireless link. Here the computer acts as an internet gateway. Through our computer we update it to a remote server from which the data are made available through a webpage to restricted users. In our project we implement this by a model. We acquire two important patient parameters, body temperature and heart pulse. The sensed analog values are digitized using the ADC inbuilt in a PIC microcontroller. The microcontroller then forwards these values to its serial port to which a zigbee is connected. At the receiver end a receiver zigbee is used to receive the values and transmit to the computer. Using VB an application is created, which displays received values and data are updated to the server using the same.data is made available to the clients through a browser in secured manner.
