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
