1. An apparatus for a sensor for self calibration, comprising:
a gas sensor assembly, comprising a plurality of gas sensors arranged in a two-dimensional array;
a membrane assembly disposed opposite to the gas sensor assembly; and
a driving assembly disposed between the gas sensor assembly and the membrane assembly and configured to selectively connect the membrane assembly with the gas sensor assembly or to separate the membrane assembly from the gas sensor assembly; wherein the membrane assembly is plate-shaped and adapted to selectively cover the plurality of gas sensors.
