Design and Development of Safety Monitoring System For Gas Leakage and Ventilation

Abstract

Every year we lose many lives due to gas leakage, lack of oxygen, or fires resulting from various heating methods or from cooking gas, as no one notices the leakage of these toxic and flammable gasses inside the house as a result of their inability to recognize the danger or avoid risks such as children and people who suffer from certain disabilities that limit the sense of smell and movement, especially in the recent period in which the Corona pandemic has spread. In this project, we will focus on preserving the safety of people and property, as well as reducing expected and unexpected accident rates, and reducing human and material losses in case of danger. Basically, we propose an ( IoT) system to maintain adequate ventilation in living rooms and prevent fires. The system takes several measures to make a quick reaction in the event of a fire or an increase in the levels of toxic gasses. So the system works to read the required values from the sensors, the reading will be transferred from the sensors to a microcontroller to be analyzed and processed, and then compared to the typical values to ensure that a defect does not occur. When a defect occurs, the system will alert the user to the presence of a defect by sending a text message and turning on the buzzer. At the same time the system will close the windows, it also turns on the water pump in the event of a fire. In the event of an increase in the percentage of toxic gasses, without the presence of a fire, the system will provide proper ventilation by opening sealed windows. The system also enables the user to monitor the status of the home through text messages. As a result, the system was built and tested to meet the project standards, and it was found to perform as expected and meet the project requirements. Therefore, our system can maintain adequate ventilation in the living rooms and prevent fires
