The project aims in designing a wearable device which is capable of tracking the location of cardiac patients and monitoring of heart rate and also alerts in case of emergency through SMS to predefined numbers.   Now a day’s technology is running with time, it completely occupied the life style of human beings. It is being used everywhere in our daily life to fulfil our requirements. We can not only increase the comfort of life but also increase the health monitoring techniques by making use of advanced technology. In this project we are making use of technology to sense serious health problems so that efficient medical services can be provided to the patient in appropriate time.   This project aims in sending alert messages in emergency times, i.e. when a person is alone in home or traveling and his heartbeat or body temperature rises or lowers then alerting messages will be send to the mobile phone, the message consist of location of that person also. Also, we can get the heart rate of the person by simply sending a pre-defined format SMS. Here we get the alerting message from the GSM modem (SMS Message) and the location of that person can be finding with the help of GPS. The GPS is the acronym for Global positioning system. GPS gives Position, velocity, time of anything located on the earth. This GPS receiver is capable of identifying the location in which it was present in the form of latitude and longitudes. The GPS receiver gets the data from the satellites.   The functioning of this device is based on the truth that the blood level circulation during expansion and contraction of heart which can be sensed by Heartbeat sensor. Depending upon the rate of circulation of blood per second the heart beat rate per minute is calculated. This device consists of a microcontroller which takes the input from the heart beat sensor and calculates the heart rate of the patient. The micro controller takes the responsibility to sending alert messages through GSM modem whenever it is necessary. The Microcontroller is programmed using Embedded C language.

 

The main objectives of the project are:

1. Design a smart watch for Real time monitoring of health status of a person.
2. Alerts in emergency to predefined numbers.
3. Works anywhere in the world (with GSM availability).
4. location tracking using GPS.
5. Battery operated device.
