Combustible gas gas sensor GM-402B

CH4semiconductorfor leak detection

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 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 simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal. Application Gas leak detection for mobile phones, computers and other consumer electronics applications; also apply for home, commercial use of the combustible gas leakage monitoring devices, gas leak detectors, fire / security detection system. Features MEMS technology, Strong construction High sensitivity to combustible gases Small sizes and low power consumption Fast response and resume Simple drive circuit, Long lifespan
