Development of a MEMS hotplate-based photoacoustic CO2 sensor

Instead of the conventional use of micro-electro-mechanical system (MEMS) hotplate for metal oxide semiconductor (MOS) or nondispersive infrared (NDIR) gas sensing, it was used for photoacoustic (PA) gas sensing. A low-cost MEMS microphone was used for the development of this MEMS hotplate PA carbon dioxide (CO2) sensor. To the knowledge of the authors, this is the first time that a MEMS ...
