Multifunctional gas safety monitoring and classification warning device

Due to the absence of automatic flameout and other essential functionalities in these devices, incidents such as gas leaks can easily lead to explosions. As a result, an autonomous safety monitoring and early warning device has been specifically developed for traditional gas stove equipment. This device is capable of activating a multi-tiered alarm and control mechanism when it reaches a predetermined threshold concentration. The main control of the Arduino Uno R3 microcontroller development board serves as the foundation for this device, which utilizes the MQ-5 gas sensor and 1602 liquid crystal display module to provide real-time gas concentration display. It also incorporates a sound and light alarm system that triggers when the concentration exceeds the predetermined threshold. Additionally, it employs a human infrared sensor and flame sensor as modules for fire detection and occupancy monitoring respectively. Any abnormal changes in these parameters will activate the sound and light alarm system. Equipped with an LED light and buzzer, this system provides real-time monitoring around gas stoves. Experimental results demonstrate excellent responsiveness under current conditions. Given its significant relevance in ensuring gas safety, this multifunctional gas safety monitoring device with classification early warning capabilities holds immense potential for market applications.
