GM-102B MEMS NO2 Gas Sensor Small Sizes And Low Power Consumption Fast Response And Resume Fast Response And Resume
Product description:
MEMS NO2 gas sensor is using MEMS micro-fabrication hot plate on a Si substrate base, gas-sensitive materials used in the clean air is 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.
Character :
MEMS technology, Strong construction High sensitivity to NO2 gas Small sizes and low power consumption Fast response and resume Simple drive circuit, Long lifespan
Application :
Mostly used in the fixed or portable NO2 detector or alarms.
