Pls help me sir for writing program for my project.It deals with sensors(temperature LM35.Humidity DHT11,Heart beat rate).
As mentioned above the sensor sensed value is display in LCD 16 x 2 display.In my project am fix the threshold value .if the measured value is decreased or increased ithe information will b send to mobile phone via GSM SIM900A .PLEASE HELP TO DEVELOP A PROGRAM FOR THE SAME. And also i include the program i had written.pls take action to correct my pgm or ur send the exact pgm to ma mail

pinMode(A4,INPUT);
lcd.begin(16, 2);
lcd.clear();
lcd.print("emergency");
mySerial.begin(9600);
Serial.begin(9600);

void loop()
{
int x=analogRead(A2),Y=analogRead(A3),z=analogRead(A4);
if((x>=35)!!(Y>=100)!!(z>=120))

switch(Serial.read())

case 's':
SendMessage();
break;
case 'r':

break;
}
if(mySerial.available()>0)
Serial.write(mySerial.read());
}}
void SendMessage()
{
lcd.setCursor(0,1);
lcd.print('x');
lcd.print('y');
lcd.print('z');
lcd.print(millis()/1000);
mySerial.println("AT+CMGF=1");

delay(100);
mySerial.println((char)26);
delay(1000);
}
void ReceiveMessage()
{

delay(1000);
}
