Abstract

This report presents the development of an Arduino-based smoke detection system with SMS alert in conjunction with a GSM module . The system is much more efficient in terms of power consumption, durability, sensing smoke and is also inexpensive when compared to other models on the market, allowing it to be used even at the household level and thus preventing any casualties in the event of an accident with the least amount of maintenance. The system consists of a few electrical components that work together to detect the presence of fire and alert people. This portable smoke detection system is constructed in such a manner that the overall status of the room or location may be evaluated at any time. The aim of this project is to prevent major accidents caused by fires at residential or industrial premises. The main objective is to detect smoke at an early stage, which allows for the fire to be put out earlier and not cause any damage. It is accomplished by implementing a Metal Oxide Semiconductor (MOS) MQ2 type gas sensor. The sensor signal analog is converted to digital by the ADC and processed by a microcontroller Arduino Uno to command activation of the buzzer and SMS (short message service); the sensor system is also capable of displaying a smoke concentration detected by the LCD in parts per million (ppm). Aside from the gas sensor, the GSM module SIM900A is also used to interact between the sensor and the user via an interface provided by the microcontroller by delivering the specific at commands. Moreover, for this project, a bundle of joss sticks are used as testing. As a result, anytime the smoke level surpasses the sensor's calibrated threshold value of 300 ppm, the sensor's resistance decreases, causing the output voltage to rise as the concentration of smoke increases. In line with the microcontroller coding, the corresponding at commands are delivered to the GSM module by the Microcontroller Arduino UNO, which is connected to the gas sensor. The GSM module subsequently sends an alarm message to the household members for further action. Other than that, this report includes all the process during the project as well as the results that were obtained after carrying out the ii project such as the user's will receive alert SMS, value of Rs/Ro and sensor’s output voltage when concentration increased, the distance of the system with source fire and the best position to place the system. Basically the input and output of the sensor, analysis of the system and the connection of the circuit will be exploited towards the success of the smoke detection system.
