Portable gas leak detection system using IoT and off-the shelf sensor node

Abstract

<p>In companies that use toxic gases in vast amounts for a range of procedures, there are a host of high-risk concerns to address. People will not be able to track or control the emission of these gases on a routine basis until it becomes harmful. Sensors are expected to actively detect leaks and alert users to any potential hazards. Gas leakage may occur at multiple locations within a single installation. As a result, sensors are implanted as close to the suspected leak site as possible, enabling them to track leakage and relay signals to a base station that is situated far away. Many sensor values are received and analyzed using a microcontroller. The generated data is encoded in the wireless module and sent to the base through the internet of things link, where it is decoded and viewed by another microcontroller. When leaks are detected, the device sends an audio and visual alert, and since the detection period is very limited due to high-speed processing, leakage situations are brought under control with minimal or no effect. Using the new IoT technology and tracking from anywhere on the network, this project offers a cost-effective and reliable solution for mitigating leakage risk.</p>
