Biological information measurement system

The present invention provides a biological information measurement system. The biological information measurement system includes a test subject-side device and a server communicable with the test subject-side device. The test subject-side device includes a sulfur-containing gas sensor reacting with a sulfur-containing gas and outputting detection data, and a signal transceiver transmitting detection data including detection data of the sulfur-containing gas detected by the sulfur-containing gas sensor to the server. The server includes a database in which the detection data is accumulated and recorded with dates and times of defecation acts by being associated with test subject identification information, and a server-side data analyzer that analyzes the physical condition of a test subject on the basis of a time-dependent variation tendency of the detection data accumulated and recorded in the database. The biological information measurement systemis capable of allowing general consumers to readily purchas
