10. Detection Principle
 Hot-wire Semiconductor Sensor
When combustible gases react with oxygen absorbed on the surface of thesemiconductor, free electrons increase in the semiconductor. As a result, theresistance of the semiconductor decreases. This resistance change is read asdifferential voltage using a bridge circuit for gas detection purpose. This type of
sensor is very sensitive and thus suitable for low concentration gas detection.
