Fire_Alarm system using atmega32

In this Project I have used :

· LM35 sensor to track the Temperature.

· Buzzer to represent the fire alarm .

· DC - Motor to represent Water Sprinkler .

This system has 3 states :

· Normal State : when Temp < 40 c . ( Nothing is On )

· HEAT State : when Temp > 40 c .(Yellow LED on )

In this stage if the temp returns back to be less than 40 c , the system will return in Normal state ( reversible ) .

· Fire state : when Temp > 60 c .(Red LED on & MOTOR is and Buzzer is on) .

In this stage the temperature cannot go down unless you entered the password (1234)

All of these features are associated with a system Password Using Keypad ! .

The project is based on Layered Architecture Software :

· Application Layer .

· HAL : Keypad , LCD , Sensors , Motors drivers .

· MCAL : ADC driver , GPIO driver .
