A hydrogen sensor includes a communication terminal, a plurality of identification terminals, and an ID setting section. The communication terminal is connected to a first communication bus or a second communication bus, and communicate with a vehicle ECU. Each of the plurality of identification terminals is set to either an open state (OPEN) in which the identification terminal is not connected to any potential or a grounded state (GND) in which the identification terminal is connected to a ground potential. The ID setting section sets an identifier in either a standard format or an extended format, according to a difference in the communication bus to which the communication terminal is connected.

A mesh filter includes a filter unit connecting an outer peripheral surface of an inner cylinder and an inner peripheral surface of an outer cylinder. The inner cylinder, the outer cylinder, and the filter unit are integrally molded by injecting a thermoplastic resin into a cavity of a mold so as to have a one-piece construction. A portion of the filter unit other than a connecting portion between the inner cylinder and the outer cylinder has square-shaped openings formed by vertical ribs formed equidistantly so as to be orthogonal to an X-axis and parallel to a Y-axis, and lateral ribs formed equidistantly so as to be orthogonal to the vertical ribs and parallel with the X-axis. The vertical ribs and the lateral ribs have rib widths (L, L) in a range from 0.07 to 0.1 mm and thicknesses (L, L) along a center axis of the inner cylinder in a range from 0.2 to 0.4 mm.

A filter unit connecting a gate connection part to an outer cylinder includes a plurality of longitudinal ribs formed at regular intervals orthogonally to an X axis and parallel to a Y axis when a virtual plane orthogonal to a central axis of the gate connection part is assumed to be an X-Y plane. A plurality of transverse ribs is formed at regular intervals orthogonally to the longitudinal ribs and parallel to the X axis, and a plurality of rectangular openings is formed between the longitudinal ribs and the transverse ribs. By injecting molten resin into a cavity from a gate opened toward a cavity portion forming the gate connection part, the gate connection part, the outer cylinder, and the filter unit are formed integrally, the rib widths of the longitudinal ribs and the transverse ribs are made constant, and the shapes of the plurality of openings are made identical.

A gas monitoring system and a gas monitoring method make it possible to identify plural gas sensors having a single specification and which are connected to one trunk line. Trunk line connectors have identification configurations for allowing information concerning positions where the trunk line connectors to be identified are arranged. Hydrogen sensors have a single specification (the same specification). When connectors of the hydrogen sensors are fitted to the trunk line connectors, the hydrogen sensors store the sensor IDs, which are assigned to the hydrogen sensors, in memory units based on the identification configurations of the trunk line connectors.
