SMOKE DETECTOR:
A smoke detector is a device that senses smoke, typically as an indicator of fire.

How does it work?
When smoke enters the chamber through the holes at the bottom, it makes the fiber contract. That makes the light blue lever , tilt downward, so the green lever also tilts down, allowing the upper electrical contact to touch the lower one. This completes the circuit and triggers the alarm.
APPARATUS:
AT MEGA 16
RESISTORS ()10 K,2K,50K
CAPACITOR(10 Uf)
LCD
GAS SENSOR MQ2
CONNECTING WIRES
POWER SOURCE
BREAD BORD
SWITCHES













CIRCUIT:


CONCLUSION:
In this project we have used AT mega16 ,burned it using super pro then used AVR studio to implement the code generating hex file for AT mega16. Then it is programmed for the sensation of smoke , the gas sensor detects the smoke and the LCD turns ON.
