Construction of Wireless Stethoscope with Noise Reduction Feature using Zigbee Module

Abstract

Stethoscope is the most generally employed tool in the health care. Sometimes hearing the patient’s heart sound or murmurs which are low in amplitude may lead to false diagnoses and this project helps to overcome several problems. The physician will be able to monitor his patient’s condition by the graph displayed using the MATLAB software in his laptop with the use of ZigBee module. MATLAB software is used for analyzing the heart sounds, so the doctor will be able to diagnoses the graph accurately. ZigBee module is employed for wireless transmission of data from the stethoscope to the doctors who are far away from the patients while the stethoscope is in contact with the patients. When immediate assistance is required i.e. when the readings cross the threshold level, a buzzer would alert the authorities for the immediate assistance. All the components could be built and controlled through the Arduino microcontroller which is easy and simple to implement. Thus our project aims at helping people and as well as doctors for easy and accurate diagnoses through the extensive use of embedded systems and wireless communication technology.
