Abstract
The proposed project aims to develop an LPG Gas Leak Detection System with Alarm Trigger and Air Filtration using Arduino Technology for Enhanced Safety in Indoor Environments, specifically targeting residential homes in Kampala, Uganda. The system addresses the critical need for enhanced safety measures against LPG gas leakage incidents in these indoor settings. The project utilizes an Arduino Uno microcontroller as the central control unit, integrated with various components such as an MQ4 gas sensor, a servo motor, a buzzer, a 16x2 LCD screen, a MOSFET, CPU cooling fans, and an LPG regulator. The MQ4 gas sensor continuously monitors the environment for any leakage of LPG gas. Upon detecting a gas leak, the sensor sends a signal to the Arduino microcontroller, which then triggers a series of actions. First, the buzzer sounds an audible alarm, and a warning message is displayed on the LCD screen. Simultaneously, the servo motor is activated to turn off the LPG regulator, effectively shutting off the gas supply. To mitigate the potential hazards of the leaked gas, the system engages CPU cooling fans to ventilate and filter the air within the indoor environment. This air filtration mechanism helps to clear the toxic gas from the room, enhancing overall safety. The project leverages the versatility and cost-effectiveness of the Arduino platform, allowing for easy customization and future enhancements. The proposed system aims to provide an efficient and reliable solution for detecting LPG gas leaks, triggering alarms, shutting off the gas supply, and filtering the air, ultimately enhancing safety measures in residential homes in Kampala, Uganda. By implementing this system in residential homes, the project seeks to contribute to the reduction of accidents and potential hazards associated with LPG gas leakage, thereby promoting a safer living environment for the local community.
