The Designed MEMS Methane Sensor Based on Pulse Power Supply

Abstract

Abstract As the power too high, the traditional catalytic methane sensor has high wiring cost and quantitative restriction in single circuit. In this paper, a new intelligent methane sensor aimed at low power consumption is designed by using low power MEMS catalytic methane cell, pulse supply mechanism and low power waste circuit. It is observed from the test that the new sensor has low power consumption and well performance.
