GM-302B MEMS Alcohol Gas Sensor Small Sizes And Low Power Consumption Fast Response And Resume Also Suitable For Drink Supervision Tomotoristsand Other Risk Operators
Product description:
MEMS alcohol 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.
Character :
MEMS technology, Strong construction Good shock resistance Small sizes and low power consumption Fast response and resume Simple drive circuit, Long lifespan
Application :
Applicable to the ethanol vapor of the place where the consumer electronics products suchasmobile phones and computers are used for testing; also suitable for drink supervision tomotoristsand other risk operators.
