IoT Based Fire Detector System Using MQ-4 and LM35 Sensor

The issue of fires is a significant concern today, as they can occur at any moment, leading to devastating loss of life and property. Fires are particularly challenging to manage in densely populated areas where houses are closely packed, allowing flames to spread rapidly. Recent years have witnessed numerous incidents with catastrophic consequences. Therefore, it is crucial to adopt effective precautions. One essential precaution is the installation of fire warning devices. Leveraging modern technology, these devices can significantly mitigate damage and save lives. This research focuses on developing a prototype capable of detecting fires and alerting the property owner about the current situation and temperature via a call. Additionally, the device will trigger an alarm if it detects the presence of gas (CH4) inside the area.
