A Low Power 4-Channel Single-Cantilever Metal-Oxide Gas Sensor Cell with Gas Identification Capability

Strategic report on MEMS based carbon monoxide sensor technology for environmental air quality monitoring using unmanned aerial vehicle

“…The researchers were designed four channel gas sensor structure and MOx material was used the researchers were used sputtering technique for deposition of SnO 2 for the sensing layer. The observed power consumption was about 8.55 mW and the optimised response is achieved for 50 ppm of hydrogen (H 2 ) as well as ammonia (NH 3 ) [90].…”
