In the vast network of pipelines that crisscross our world, an invisible threat hides, quietly waiting to unleash disorder and destruction. At the core of this looming danger lies with combination of gas detection failures and low-sensitive gas sensors. This alarming partnership creates a vulnerability that can lead to explosive disasters, endangering both human safety and the environment. In the pursuit of cost- effectiveness, low-sensitive gas sensors have been incorporated into pipeline systems. While these sensors offer economic benefits, they inadvertently expose pipelines to a grave risk. By failing to detect subtle shifts in gas concentrations, they allow dangerous compounds to accumulate undetected, creating a ticking time bomb within the pipelines.At the core of gas leakage detection systems lie gas sensors. In the contemporary market, a multitude of gas sensors is available, encompassing varieties of mechanism such as metal oxide, capacitive, resistive, optical and calorimetric sensors. Each of these sensors exhibits reduced sensitivity when faced with low concentrations of gas leaks, along with prolonged response times, diminished repeatability and elevated noise floors.
