Abstract
Provided are a gas concentration measurement system, gas concentration computation section, and gas concentration measurement method enabling high-accuracy gas concentration measurement. The gas concentration measurement system includes: a gas concentration measurement section () including a light-emitting element () and a first sensor element; a light-emitting element drive section that drives the light-emitting element; a signal acquisition section () that acquires at least an output signal of the first sensor element, a first drive signal that is a first voltage value or first current value of the light-emitting element, and a second drive signal that is a second voltage value or second current value of the light-emitting element; and a computation section () that computes gas concentration based on signals acquired by the signal acquisition section. The computation section, based on the first and second drive signals, corrects the output signal of the first sensor element and computes the gas concentration.
