MEMS combustible gas sensor is using MEMS micro-fabrication hot plate on a Si substrate base, gas-sensitive materials used in the clean air with low conductivity metal oxide semiconductor material. When the sensor exposed to the gas atmosphere, the conductivity is changing as the detected gas concentration in the air. The higher the concentration of the gas, the higher the conductivity. Use a simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal.
Applications:
Gas leak detection for mobile phones, computers, and other consumer electronics applications; also apply for a home, commercial use of the combustible gas leakage monitoring devices, gas leak detectors, fire/security detection system.
