Environmental humidity is an important factor influencing the performance of metal oxide gas. Metal oxide sensors are compact and low cost but require more power than electrochemical sensors. Many metal oxides are suitable for detecting combustible, reducing, or oxidizing gases.

Investigations have indicated that the gas sensing process is strongly related to surface reactions, so one of the important parameters of gas sensors, the sensitivity of the metal oxide based materials, will change with the factors.
This paper therefore investigates the effects of these two factors towards gas.
Metal oxide gas sensors have been widely used in portable gas detection systems because of their advantages such as low cost, easy production, compact size and simple measuring electronics [5,6].

Gas sensitivity was preferred main gas sensor parameter.
The conductometric semiconducting metal oxide gas sensors currently constitute one of the most. Conductometric semiconducting metal oxide gas sensors have been widely used and investigated in the detection of gases. Metal oxide gas sensors have been widely used in robotics application to perform remote and mobile gas sensing. In this study, metal oxide gas sensors by nanostructures were investigated comprehensively.
However, the performance of such sensors is significantly influenced by the morphology and structure of sensing materials, resulting in a great obstacle for gas.
2. metal oxides for gas sensors. Sensitivity and influencing factors, sensors, 10. Based on the pioneering work of yamazoe (1991) on performance improvement of metal oxide (mox) semiconducting gas sensors with nanometric crystallite sizes, many substantial efforts have been spent to produce nanostructured materials [e.g., nanoparticles (nps), nanotubes (nts), nanobelts, and nanowires (nws)] demonstrating increased sensitivity and selectivity and. The fabricated sensors that are.
