How Does a TVOC Sensor Actually Work?

MOS (metal oxide semi-conductors) work by heating a thin film, or surface, of metal-oxide particles. In Kaiterra products, this is a thin film of metal-oxide nanoparticles. This film is heated to around 300’C (hence the warm up period after turning on a Kaiterra device). During operation, oxygen particles will be adsorbed on the surface, and ...
