This invention relates to a low-cost device for detecting methane gas using a silicon Schottky diode. The device works by using a light source, such as an IR lamp or solar radiation, and measures changes in current to detect the presence of methane. Methane absorbs specific wavelengths of light, causing a drop in current that the device can detect. The Schottky diode is chosen for its fast response time and ease of integration with existing technologies. The device is effective in various environments, including underwater, and operates across a wide temperature range. It offers a reliable and portable solution for methane detection in both industrial and domestic settings.
