Fire alarm at system at office building using GSM module / Alif Iqbal Ahamat Mahmod

This thesis presents a development of a fire alarm system at office building using GSM module with the motivation to provide a solution to help people escape from being trapped in office buildings safely in the event of a fire. One of the main reasons people were trapped during fire occurrences in a building is limited visibility due to heavy smoke hence being unable to find the way out. Furthermore, the late detection of fire also causes panic which consequently causes the evacuation process to be delayed and eventually could lead to a more serious incidence, i.e. fatal. This project uses Arduino UNO as the microcontroller, where the fire alarm system senses unusual smoke and a rise in temperature using a smoke sensor and a temperature sensor respectively in the occurrence of fire. Then, the microcontroller will send signals to control the outputs, i.e. alarm, LCD display, SMS notification, LED flash and automatic door. The simulation model of the system was developed prior to the hardware prototype development using Proteus software where the coding for the microcontroller was designed. The results show that the simulation model of the fire alarm system is able to detect fire and outputs simulated results expectedly. On the other hand, the developed hardware prototype is also able to detect fire and provide the expected output, i.e. automatically sending notifications of fire via SMS, warning through the alarm and displaying information on LCD, automatically opening exit door and flashing lights via LEDs to provide exit route. In conclusion, the developed fire alarm system using GSM operates successfully in detecting fire and provides multiple outputs as notifications and countermeasures during fire events in an office building
