Gas sensors play a critical role in continuously monitoring emissions generated by both household and industrial operations. Increasing emphasis on reducing harmful gas emissions from essential industries is significantly boosting market demand. Developments in smart sensor technologies are enabling manufacturers to design more sophisticated detection systems. Drone-based gas leak detection solutions are also emerging, offering improved safety for pipeline monitoring. An example is ABB Ltd.’s HoverGuard system, introduced in April 2021, which is capable of detecting, mapping, and quantifying gas leaks from up to 100 meters away.

Industries such as chemical processing, oil & gas, and power generation rely heavily on gas sensors to identify dangerous levels of gases including carbon monoxide, carbon dioxide, hydrocarbons, and ammonia. Excessive emissions of these gases can pose severe risks to human health. Power generation facilities, in particular, utilize methane—a highly flammable greenhouse gas—making reliable detection systems essential. Innovations such as electrochemical sensors and Non-Dispersive Infrared (NDIR) sensors are being developed to better detect methane and other industrial gases.
