A complete project kit to build a working gas leak alarm that detects smoke, butane, methane, and LPG. The MQ-2 sensor reads gas concentrations while the ESP32 processes the data and triggers the NE555-driven alarm circuit when dangerous levels are detected. Includes everything you need to build the circuit on the included breadboard with power supply. Follow our step-by-step project guide to go from unboxing to a working safety device in under 2 hours. WiFi capability means you can add remote notifications to your phone. All components tested for compatibility.
