A gas Detector is an electronic device that is installed in a building to detect the presence of gas to prevent fire outbreak. An automatic alarm system is designed to detect the unwanted presence of gas by monitoring environmental changes associated with combustion. In general, an alarm system is classified as either automatically actuated, manually actuated, or both. Automatic alarm systems are intended to notify the building occupants to evacuate in the event of a gas leakage or other emergency, report the event to an off-premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and gas. The gas detector system composes of a light dependent resistor (LDR) which works as a gas sensor. Light dependent resistor is a type of resistor with high resistance in the presence of light and which reduces in its resistance when gas passes through the surface. The aim of this project is to design and construct a fire alarm for a building that will detect the presence of gas leakages in a building.
