The LPG Gas and Flame Detector with LCD is a fire and gas leak detection system designed for students, hobbyists, and engineering projects. It features an MQ2 gas sensor to detect LPG leaks and a 5-channel flame sensor for fire detection from multiple directions. The LCD displays real-time gas concentration and fire status, while an alert buzzer provides instant warnings. The system is powered by rechargeable 18650 Li-ion batteries with a TP4056 charging module. The project is fully assembled on an MDF board for ease of use and stability. Ideal for science exhibitions, engineering projects, and home safety applications.
