A toilet seat apparatus according to an embodiment includes: a toilet seat on which a user sits; a light emitting unit including a light emitting element that emits light; a light receiving unit including a light receiving element that receives light; and a control unit that controls energization of the light emitting element and application of voltage to the light receiving element, in which the control unit performs light reception control including transmitting a control instruction to open an electronic shutter to the light receiving element and energizing the light emitting element so as to permit reception of the reflected light from feces, and performs control of setting an interval from a start of execution of one light reception control to execution of light reception control subsequent to the one light reception control, to 0.2 milliseconds or more.

Toilet seat apparatus and excrement detection apparatus

A toilet seat apparatus according to an embodiment is a toilet seat apparatus to be placed on an upper part of a toilet bowl having a bowl unit that receives excrement, the toilet seat apparatus including: a toilet seat on which a user sits; a light emitting unit including one or more light emitting elements that emit light in a front direction; a light receiving unit including a light receiving element that receives light; and a housing in which the light emitting unit and the light receiving unit are arranged, in which the one or more light emitting elements are arranged in parallel with the light receiving unit or in front of the light receiving unit in a side view or a top view of the housing.

A toilet seat apparatus according to an embodiment is a toilet seat apparatus to be placed on an upper part of a toilet bowl, the toilet seat apparatus including: a toilet seat on which a user sits; a light emitting unit that emits light; and a light receiving unit that receives light; first memory that stores data received by the light receiving unit; and an arithmetic processing device that executes transfer of data received by the light receiving unit to the first memory, and analysis and deletion of data stored in the first memory, in which the arithmetic processing device transfers the data received by the light receiving unit to the first memory, and deletes the data temporarily stored in the first memory when the data has been analyzed to be data that is not data based on the reflected light from falling feces.

The biological information measurement system of the present invention includes a test subject-side device provided in a toilet installation room, and a server communicable with the test subject-side device, the test subject-side device includes a sulfur-containing gas sensor sensitive to sulfur-containing gas and outputting detection data, a transmitter-receiver transmitting measurement data including detection data of the sulfur-containing gas detected by the sulfur-containing gas sensor to the server, and the server includes a database in which measurement data including detection data of sulfur-containing gas detected by the sulfur-containing gas sensor is accumulated and recorded with dates and times of defecation acts by being associated with test subject identification information, and server-side data analyzer that analyzes physical condition of a test subject on the basis of a time-dependent variation tendency of the measurement data accumulated and recorded in the database.
