10. Detection Principle



Hot-wire Semiconductor Sensor

The sensor is constructed of a metal oxide semiconductor that is sintered in a ball on

a platinum wire coil that functions as both a heater and electrode. When combustible

gas is absorbed by the surface of the metal oxide semiconductor, the electrical

conductivity changes due to an oxidation reaction.
