DESIGN AND CONSTRUCTION OF A FIRE DETECTORUSING MQ-2 SENSOR

DESIGN AND CONSTRUCTION OF A FIRE DETECTORUSING MQ-2 SENSOR

This project is titled design and construction of an automatic fire alarm. Fire alarm is an electronics device that is stored in a building to detect the presence of fire accident. An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire 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 smoke.
This fire alarm system composes of a MQ-2 smoke sensor. This smoke sensor detects the concentrations of smoke in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of flammable gas of 300 to 10,000 ppm. The sensor can operate at temperatures from -20 to 50°C and consumes less than 150 mA at 5 V. The aim of this project is to design and construct a fire alarm for a building that will detect the presence of fire (smoke) accident in a building.
