GM-512B MEMS Breath Smell Gas Sensor High Sensitivity To H2S Alcohol And Gas Small Size High Sensitivity Low Power Consumption
Product description:
MEMS breath smell 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. Using simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal.
Character:
MEMS technology, strong structure High sensitivity to H2S, Alcohol, and gas Small size, High sensitivity, Low power consumption Fast response and resume, Simple drive circuit, Long lifespan
