3. Project Overview State-of-the-art system allowing doctors to monitor patients blood pressure, body temperature and heart beat (ECG).State-of-the-art system allowing doctors to monitor patients blood pressure, body temperature and heart beat (ECG). –Device strapped to the patient. Heart beat and temperature are measured by the sensors present in the device. –Measured data sent to the Computer via RF. –Doctors and nurses are warned by alarm system present in the device through a speaker. –Heart beat and body temperature are constantly displayed on the LCD.

4. Project-Specific Success Criteria Ability to obtain body temperature, heart rate, and blood pressure from sensors to the microcontrollerAbility to obtain body temperature, heart rate, and blood pressure from sensors to the microcontroller Ability to send / receive / decode RF SignalsAbility to send / receive / decode RF Signals Ability to display health information to the patient via LCDAbility to display health information to the patient via LCD Ability to alert Patient about an emergency through a speakerAbility to alert Patient about an emergency through a speaker Ability to identify emergency and send signals to the doctors/nurses.Ability to identify emergency and send signals to the doctors/nurses.
