ABSTRACT:

The health monitoring and controlling system in the hospital need to be continuously monitor by the doctors or others staff of the hospital. These health monitoring system include heart beat monitoring system, oxygen monitoring system, saline monitoring system, blood pressure monitoring and many such system where continuous monitoring and parameter checking required. Most of the current health monitoring and controlling system having interfaces like monitor, LCD display and some control switches. It is impossible for the doctors and nurses and other hospital staff to continuously work only for single patient. These interfaces are fixed and connected to the health monitoring and controlling system using wires. We can provide these interfaces to the doctor using wireless network link like ZigBee.The characteristics of ZigBee like low power ,low cost, range up to 100 meter and network forming ability make ZigBee technology an ideal choice for wireless monitoring and controlling network in health monitoring systems.

In our proposed system we are using ZigBee module, ARM 2148 microcontroller system and one temperature sensor who monitor the temperature continuously. This module continuously sends the temperature to the doctor who having ZigBee enbabled ARM 2148 microcontroller system. The doctor can set certain parameters in the microcontroller program so if the temperature range exceeds that parameter it will give alert message. The doctor will send corrective control code from his wireless terminal to patient terminal.
