Gas leakage is a critical global threat, frequently resulting in property destruction and loss of life. To address this, this project introduces a multi-functional Smart Gas Leak Detector built with a Micro:bit and MQ-4 sensor. The device provides real-time monitoring, triggering LED, buzzer, and 5x5 dot matrix alerts upon detecting hazardous gas. Additionally, it features an integrated security system that sends Telegram notifications during break-ins. Protected by a custom 3D-printed housing, this compact, low-cost prototype offers a proactive solution for home safety, combining gas detection and anti-theft technology to safeguard lives and property effectively.
