Design CuO-doped SnO2 Thick film Gas Sensor for H2S Using ANN Technique

Abstract

Environment cause for concern stirred up a greater interest in the expansion of gas sensors for toxic gas detection The semiconductor materials and metal oxide material are found to be appropriate in the favors of untruth of thick film gas sensor. The suitability of these materials is because the cost was very low as compared to other materials. Nevertheless, different accessibility approach for vapors detection, solid-state gas sensor suggested a better choice due to their rugged monitoring construction and sufficiently low cost. Among the various micro-technologies used for fabrication of gas sensors thick film sensors offer benefit over other technologies in terms of cost, strength, less susceptibility to contamination, more sensitivity, high productivity and automation along with the running out of time appropriate transfer from paradigm model products. Some disadvantages associated with thick film sensors are their low selectivity and high-power consumption. The Internet of Things (IoT) is the current development in healthcare and domestic air grade supervision magnifies the business requirement on behalf of reducing the size of gas sensors. Metal Oxide Gas Sensors established on frequently utilized micro hotplates falsification over a Micro-Electro- Mechanical System (MEMS) field of technological advancement predominate the market appropriate performance and lower expense. Gas sensors have been mostly implementing in dissimilar domains, alike of agriculture, automotive industry, home automation system for inside air quality controlling and environmental supervision. The 1% CuO doped SnO2 based thick film fabricated sensors regression with H2S toxic gas (250 ppm- 1500 ppm) was demonstrated in the temperature wide ranges of 150 and 350?C.
