MEMS gas sensor module

product details

The digital MEMS gas sensor consists of a Si based micro heating plate based on MEMS technology and a metal oxide semiconductor gas sensing material with low conductivity in clean air. When there is a detected gas in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit. The higher the concentration of gas, the higher the conductivity of the sensor. This sensor has high sensitivity, is compact and precise, with two preset pins for alarm trigger signal output, and can be widely used in many fields such as environmental safety and portable instruments.
