The document describes a heart rate and temperature monitoring system that uses sensors to detect a patient's vital signs and send alerts in emergency situations. The system includes: (1) Sensors to measure heart rate and temperature, (2) An Arduino microcontroller to process the sensor readings, (3) An Android phone for GPS location, (4) An application server to analyze the data and send SMS alerts if vital signs are abnormal, along with the patient's location. Pseudocode and diagrams are provided to illustrate how the different components communicate and function as part of the monitoring system.

Sequence Diagram :

10. 1. Pseudo code for sensors:
Heartbeat sensor:
Output : heartbeat(digital value)
Begin
Heartbeat sensor connect to pin13
Up : if receiver receives IR rays
Make output 1
Else
Make output 0
Go to Up
End
Component Design :

11. Temperature sensor:
Output : temperature(analog value)
Begin
Temperature sensor on pinA0
Up: send analog voltage to A0
Microcontroller convert analog to digital
Store result in variable
Go to Up
End

12. 2. Microcontroller Module :
Input: heartbeat(digital value),temperature(anolog value)
Output: temperature(digital value) & heartbeat(frequency)
Begin
Initialize heartbeat sensor and temperature sensor
Label : microcontroller check pin13
If pin13 == high
Serial port send(temp)
Go to Label
End

13. 3. Pseudo code for android phone :
Input: start application
Output: latitude & longitude
Begin
Initialize GPS in android
Lat=0;
Lng=0;
Label : determine location
Lat= current latitude
Lng= current longitude
Send latitude & longitude to application server
Go to Label
End

14. 4. Pseudo code for Application server :
Input: temperature(digital value),heartbeat(frequency),latitude,
longitude, phone number
Output: heartbeat & abnormal condition
Begin
Initialize timer
Open serial port
Timer start
Mainloop : count=0;
Label : read from serial port temp
Display temp
Count++;
If timer time end
Go to Disp
Else
Go to label
Disp : display counter (heartbeat)
Go to Mainloop
End

15. Checking abnormal condition:
Begin
Read heartbeat
Read temperature
heartbeat  count * 12
If ((heartbeat<60) && (heartbeat > 80))
Fetch phone number from database
Send SMS
End

19. Functional requirements Components
.
1. The system should have an interface to
display vital parameters like heartbeat
and temperature values in real time.
Heart Beat and Temperature Sensor
Module
2. The system should also display the
current location of the patient on the
interface.
GPS Receiver Module
3. The system should have facilities to
store cell numbers of concern person
to be contacted in case of emergency.
Calculates whether the given values
of temperature and heartbeat are
normal or not.
Application Server Module
4. Send Temperature to the serial port at
the frequency of the heart beat
Arduino Microcontroller Module
