GM-502B MEMS VOC Gas Sensor Low Power Consumption High Sensitivity Fast Response And Resume For Gas Leak Detection For Mobile Phones Computers And Other Consumer Electronics Applications
Product description :
MEMS VOC 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.
Characters:
MEMS technology, strong structure Low power consumption High sensitivity Fast response and resume Simple drive circuit
Application :
Gas leak detection for mobile phones, computers and other consumer electronics applications, also for breathing gas detection control, smoke alarm indoor etc.
