Review of Patient Alert System

Abstract: The wireless monitoring of patient have a great importance in the field of medical. With the help of micro sensors which are integrated into wireless communication networks, the physiological parameters of patient can be remotely collected and monitoring using traditional medical instruments can be avoided. In this project the monitoring of the patient is done by the doctor continuously without actually visiting the patient. Here, we make use of various sensors to sense the body parameters like pulse rate, temperature, blood pressure etc. This sensed signal is transmitted to Node MCU to update the data continuously. Using ADC which will convert this analog data into digital data through internet web portal, the data is sent to the monitor screen of the doctor�s cabin wirelessly. Hence, doctor can access the patient from anywhere.
