Sensor system and gas system

A sensor system, comprising:

• a pipe;
• and
• at least one sensor configured to detect a detection target substance in the pipe,
• the at least one sensor including:
• a base,
• a first detection part, and
• a second detection part,
• the base including a first base region and a second base region,
• the first detection part including a first support part, a first connection part, and a first detection element,
• a position of the first detection part with respect to the first base region being fixed,
• the first connection part being supported by the first support part,
• the first connection part supporting the first detection element,
• a first gap being provided between the first base region and the first detection element,
• the first detection part having a first area of the first detection element, a first connection part length of the first connection part, a first connection part width of the first connection part, a first connection part thickness of the first connection part, a first connection part material of the first connection part, and a first distance, the first distance being a distance between the first base region and the first detection element,
• the second detection part including a second support part, a second connection part, and a second detection element,
• a position of the second support part with respect to the second base region being fixed,
• the second connection part being supported by the second support part,
• the second connection part supporting the second detection element,
• a second gap being provided between the second base region and the second detection element, and
• the second detection part having at least one of a second area different from the first area of the second detection element, a second connection part length different from the first connection part length of the second connection part, a second connection part width different from the first connection part width of the second connection part, a second connection part thickness different from the first connection part thickness of the first connection part thickness, a second connection part material different from the first connection part material of the second connection part, or a second distance different from the first distance, the second distance being a distance between the second base region and the second detection element.
