GM-802B MEMS NH3 Gas Sensor High Sensitivity To NH3 Gases Small Sizes And Low Power Consumption Widely Used In Gas Detection Of Refrigerators Ammonia Leak Detection In Cold Storage
Product description:
MEMS NH3 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 High sensitivity to NH3 gases Small sizes and low power consumption Fast response and resume Simple drive circuit, Long lifespan
Application :
Widely used in gas detection of refrigerators, ammonia leak detection in cold storage, andventilation control in agricultural breeding.
