Fire Alarm System GSM based using Arduino

Did you know 87% of fire damages occur due to lack of early fire detection but Now we will try to Reduce this Percentage with the help of Technology so let,s Start
When a fire occurs the Gsm Module will send an SMS to a specified user's Mobile numbers that "fire occurred in New Room" or anything you can replace this message with your Own string.
We set Temp Threshold Value in code if(Temp_alert_val>45) when temperature reaches to 45c it will send SMS to a user Mobile Number that fire Occurred you can Replace the temperature value by your Own but remember that normal Room temp is nearly equal to 25c before setting your Temp threshold first make sure what is your Room temp and set the Threshold value on the basis of Room temp.You can Replace this Mobile number by a person Cellphone number to receive a Fire alert SMS ("AT+CMGS=\"+9195440000000\"\r").
