MST130-K tubular gas smoke sensor Semiconductor sensing series gas sensor
MST130-K gas-sensitive material used by
the gas sensor is tin dioxide (SnO2), which has a
low conductivity in clean air. When combustible
gas exists in the environment of the sensor, the
conductivity of the sensor increases with the increase of combustible gas
concentration in the air. A simple circuit is used to convert the change in
conductivity into an output signal corresponding to the concentration of the gas.
