GM 512B Gas Sensor MEMS Process Hydrogen Sulfide Breath Monitoring
GM 512B Gas Sensor MEMS Process Hydrogen Sulfide Breath Monitoring
GM-512B MEMS Process Mini Breath Detector For Breath Gas Sensor
Features:
Product description
MEMS breath gas sensor utilizes MEMS process on Si base substrate
On the fabrication of a microhot plate, the gas-sensitive material used is conductive in clean air
Lower metal oxide semiconductor materials. When there is detected gas in the ambient air
The conductivity of the sensor changes when the body exists. The higher the concentration of the gas, the higher the transmission
The higher the conductivity of the sensor. A simple circuit can be used to change the conductivity
To an output signal corresponding to the concentration of the gas.
Sensor characteristics
This product adopts MEMS process, strong structure, high sensitivity to hydrogen sulfide, alcohol,etc. With small size, low power consumption, high sensitivity,
Quick response recovery, simple driving circuit, good stability, long life and so on.
Main application
Mini breath detector.
