Efficiency and Performance Evaluation of an Early Fire Detector Device Using an ESP32 Wireless Sensor Network

Fire detectors and monitoring systems have been proven to save many lives, making them a promising investment. A fire detector is well acknowledged as one of the best preventive measures to avoid serious fire incidents. Nevertheless, there aren't many fire prevention measures used in residential areas. As a result, an early fire detection device was created that uses an ESP32 wireless sensor network to gather information about the fire, such as its location, temperature, humidity, pressure, and gas content. It is a low-cost fire detector with a graphic interface that can be used with a mobile application to immediately track and log the temperature, humidity, pressure, and gas concentration in its coverage area. The prototype's efficiency and reliability were demonstrated in this investigation using the ANOVA test and a reliability percentage test. According to test results, the prototype can detect fire within 30 seconds and gas within 10 seconds at mounting heights of 2.5 to 3 meters and spacings of up to 5 to 10 meters. There is a one-minute delay after the initial notification and email are issued in each sensor node for each fire and gas detected.
