MEMS Breath Gas Sensor GM 512B For Mini Smell Breath Detector

Product Description
MEMS Breath Gas Sensor GM 512B For Mini Smell Breath Detector



Mini Breath Detector With MEMS Breath Gas Sensor GM-512B



Features:

MEMS breath gas sensor uses MEMS process to make micro-hot plate on Si substrate. The gas-sensitive material used is metal oxide semiconductor material with low conductivity in clean air. When the detected gas exists in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit is used to convert the change in conductivity into an output signal corresponding to the concentration of the gas.

MEMS process, strong structure, high sensitivity to hydrogen sulfide, alcohol, acetone, etc

Small size, low power consumption, high sensitivity, fast response recovery

The driving circuit is simple, stable and long life
