IOT Based Gas Detection System by Using Arduino Uno

In today’s society, the safe handling of fuels and gases is paramount to prevent accidents and ensure the well-being of individuals and industries. This research endeavors to address these concerns by developing an innovative IoT-based gas detection system. The system aims to detect gas leaks promptly and take preventive actions to mitigate potential hazards effectively. At the core of this system lies the MQ6 gas sensor, renowned for its proficiency in detecting various gases commonly encountered in both residential and industrial settings, including LPG, i-butane, hydrogen, methane, smoke, and alcohol. While providing valuable insights into gas presence, the sensor operates within an acceptable margin of error, indicating trends rather than precise gas concentrations. Upon detecting a potential gas leak, the system automatically initiates precautionary measures to safeguard against accidents. These measures include the swift shutdown of the main gas supply after a predefined period, effectively minimizing the risk of potential hazards. Moreover, the integration of a Wi-Fi module enhances the system’s functionality by enabling real-time alerts to be transmitted to the system owner. In the event of a gas leak, immediate notifications are dispatched, allowing for prompt intervention and preventive actions to be taken. By combining the capabilities of the MQ6 gas sensor with advanced IoT technology, this gas detection system offers a proactive approach to gas safety, empowering users with timely information and tools to mitigate potential risks effectively.
