Abstract: A gas detection system includes a sensor unit that outputs a voltage corresponding to a concentration of a specific gas, a supply unit, and a control unit. The supply unit is capable of supplying a sample gas and a purge gas to the sensor unit. The control unit controls the supply unit to alternately supply the sample gas and the purge gas to the sensor unit. The control unit acquires a voltage waveform output by the sensor unit and detects a type and concentration of a gas contained in the sample gas, using a multiple regression analysis using characteristics of the voltage waveform as explanatory variables.

Abstract: A gas collection device is installed in a toilet including a toilet seat and a toilet bowl. The gas collection device includes a flow path connected to a predetermined tank, and an introduction portion that introduces a sample gas into the flow path. The introduction portion is located between the toilet seat and the toilet bowl, or located inside or above the toilet seat. The introduction portion does not protrude toward an inside of the toilet bowl from a rim portion of the toilet bowl when located between the toilet seat and the rim portion. The introduction portion does not protrude toward the inside of the toilet bowl from the toilet seat when located inside or above the toilet seat.

Abstract: A sensor module includes a sensor that detects a first component, a first flow channel to supply a sample fluid to the sensor, and a second flow channel to supply a reference fluid to the sensor. The reference fluid includes a second component different from the first component included in the sample fluid. The second flow channel includes a first filter that reduces the amount of the first component in the reference fluid.
