GM-512B H2S Gas Sensor For Mini Smell Breath Detector Semiconductor
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, etc
Small size, low power consumption, high sensitivity, fast response recovery
The driving circuit is simple, stable and long life
Specifications:
| Product type | MEMS breath gas sensor | 
| Standard package | ceramic package |
