- Product Code: MICS-6814 Gas Sensor Module Air Quality CO VOC NH3
- Availability: In Stock
The MiCS-6814 is a compact MOS sensor with three fully independent sensing elements in one package. It is a robust MEMS sensor for the detection of pollution from automobile exhausts and for agricultural and industrial odors.
Sensor configuration:
The silicon gas sensor structure consists of an accurately micromachined diaphragm with an embedded heating resistor and the sensing layer on top.
The MiCS-6814 includes three sensor chips with independent heaters and sensitive layers. One sensor chip detects oxidizing gases (OX), the other sensor detects reducing gases (RED), and the other sensor detects NH3. The internal connections are shown above.
Detectable gases:
- Carbon monoxide CO 1 - 1000 ppm
- Nitrogen dioxide NO2 0.05 - 10 ppm
- Ethanol C2H5OH 10 - 500 ppm
- Hydrogen H2 1 - 1000 ppm
- Ammonia NH3 1 - 500 ppm
- Methane CH4 >1000 ppm
- Propane C3H8 >1000 ppm
- Iso-butane C4H10 >1000 ppm
