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, acetone, 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.
