    • A gas sensor having a large operation current and being operated at a relatively low temperature includes a substrate having a first surface and a second surface. A sensing area is provided on the first surface for increasing the conductivity across it when the sensing area detects a certain gas. A controlling area is provided on the first surface and beside the sensing area for permitting a tunneling current to pass therethrough when the sensing area cannot sense a certain gas or when the gas sensor is adapted to be sufficiently supplied with power. This control area prevents the tunneling current from being generated when the sensing area detects certain gas and thus the conductivity is increased, so that when the first and the second surfaces are electrically connected to the power supply. The gas sensor will be in an on state when the gas sensor cannot sense there is the certain gas and be in an off state when the gas sensor detects the presence of certain gas. This gas sensor can avoid a dangerous explosion resulting from a flammable gas at a relatively high temperature. The gas sensor possesses a relatively short response time.
