Abstract
A gas sensor, a gas concentration detection system and a method of manufacturing the gas concentration detection system are disclosed. A gas sensor carries an individual information identifying section, which stores unique individual information related to the gas sensor. The individual information identifying section includes a two-dimensional information code readable with an image recognition device. The individual information identifying section includes a two-dimensional information code readable with an image recognition device. The gas concentration detecting system comprises, in addition to the gas sensor and the image recognition device, an engine control unit operative to correct a sensor output readout value, which is actually read out from the gas sensor, depending on information related to a sensor output value included in the information code.
