1.Abstract
The whole aim of this project is to design a fire sensor, the implementation of this
project was performed using LM 35 sensor ,UNO board and LCD screen the output was
to be simulated in a PROTEUS simulation and the constrains of fire were to be set as 60
degree Celsius and any temperature above this would give an alarming display on the
LCD screen.

lcd.clear();
}
if(A >= min_temp)
{
digitalWrite(fan, HIGH);
lcd.setCursor(0,0);
lcd.print("THERE'S FIRE");
lcd.setCursor(5,1);
lcd.print(A/2-1);
lcd.setCursor(7,1);
lcd.print("c");

lcd.clear();
}
}
Result:
A temperature sensor was designed using LM 35 temperature sensor wherein the limit of fire was
set as 60 degree Celsius , the program was designed with the above temperature constrain and
dumped into an UNO board in PROTEUS environment and the output result of fire was displayed on
the LCD screen.
