Abstract

This project entitled Development of an Intelligent Exhaust Fan using Lpg Sensor,Temperature Sensor and Smoke Detector.The Arduino as a controller between gas sensor MQ,LM35 temperature sensor,buzzer and fan.This system is implemented for safety purpose so that household can be alert of accident in their house by detect gas leakage and hot temperature.This is because gas is very dangerous if it is leaked.It is very useful in daily life and very important but at the same time it is also harmful to humans and the consequences of accidents that arise from the gas leak are terrible.Human careless is also one of the reasons this system is implemented so it can save people from fire accident.One of the characteristics of LPG gas is that it is difficult to impact because it does not smell at the beginning but it is extremely flammable as it is in the form of liquid.Therefore it is very important that the system is implemented at which is mainly target at home kitchen site.The main objective of this project is to activate the fan when there is a present of gas leakage,hot temperature and thick smoke. The second objective is to enable the buzzer when there is a present of gas leakage,hot temperature and thick smoke.The third objective is to save household from fire accident which cause in dead.The project will work when gas sensors detect gas leakages and the fan and buzzer will be in active state.Once its detect,the gas sensors will send signals to receiver.Next,when the temperature is exceeding the room temperature,it will transmit the signal to the receiver through Bluetooth.In this project, MQ-2 gas sensors will be used to detect gas leakage,the buzzer will be used as a warning when a gas leak occurs. The fan will act as the prevention system so that the air contained gas will be reduced. Finally this project can safe household from fire accident.
