Patent ID: 6883364

Claim:
A sensor module configured for use with a sensing apparatus comprising a housing that defines a receptacle, the sensor module comprising: a casing sized and configured to be received in the receptacle of the sensing apparatus; a sample chamber; an inlet port configured to be releasably engageable with a first port connection of the sensing apparatus when the sensor module is received in the receptacle, the inlet port receiving a test sample from the sensing apparatus and directing the test sample to the sample chamber; an outlet port configured to discharge the test sample from the sample chamber; at least one sensor located within or adjacent to the sample chamber and configured to provide a distinct response when exposed to one or more analytes located within the sample chamber; and an electrical connector configured to be releasably engageable with a mating electrical connector of the sensing apparatus when the sensor module is received in the receptacle, the electrical connector transmitting the characteristic signals from the at least one sensor to the sensing apparatus, wherein the sensor module is configured to be received in the receptacle by concurrent engagement of the inlet port, the outlet port, and the electrical connector.
