TVOC monitoring | Know about Total Volatile Organic ...

· When a metal oxide semiconductor-based hydrogen sulfide monitor is exposed to an air sample, the VOC molecules react on the metal oxide surface of the sensor and dissociate into charged ions that alter the resistance of the film. Further, this interaction is measured as a signal and is converted to the gas concentration. However, the energy consumption of such VOC monitors is higher when ...

VOC Sensors - Belimo

Today, metal oxide semiconductor sensors are almost exclusively used as VOC sensors in heating, ventilation and air-conditioning technology. This sensor element measures the conductivity of the nanocrystalline metal oxide that is applied to a substrate. These sensors only permit the measurement of a relative gas concentra-tion. As a result, it is not possible to specify a measuring range or accuracy. …

Branch-like NiO/ZnO heterostructures for VOC sensing ...

· Clearly the conduction band offset is large than that of the valence band offset, that causes a decrease in the conductance (increase in resistance) of the heterojunction sensors as compared to the NiO based sensors. The increase in the resistance of the heterojunction sensors also indicates that the p-n junction has been successfully formed.
