Metal Oxide Semiconductor (MOS)

Designed for use with the MICS-EK1 Metal Oxide Semiconductor Gas Sensor Evaluation Kit. Semiconductor gas sensors combine thermal, chemical and electrical effects. A sensing layer, composed of a metal oxide, generally SnO2, is heated by a heater structure. While chemicals are absorbed on its surface, the electrical conductivity changes locally; leading to a change in the electrical resistance. Analyzing the modifications of the resistance over time, compared with reference values, gives information about variable gas concentrations.
