Abstract: This paper deals with development of microcontroller based health monitoring system for heartbeat, temperature and oxygen using Zigbee. Now a days, nation population increases demands for caretaking because of these reason monitoring system are the most important system. In this paper we use wireless sensor network based on Zigbee technology. This monitoring system consists of Zigbee based network, microcontroller and three types of sensors which are heartbeat sensor, temperature sensor, oxygen sensor. These sensors are connected to the patient and the output is directly displayed on LCD through Zigbee. The output from the sensor is analog values it is converted to digital and processed by using microcontroller and it will be respond in LCD or computer display.
Keywords: Heartbeat sensor, Microcontroller, Oxygen sensor, Temperature sensor, Zigbee network.
