摘要： A sensor device is disclosed, including a database, and a processing apparatus. The database includes, for multiple different first types of objects, a first output data which are output data of an optical system acquired beforehand for each of the first objects in a case in which a surface of one side of the first object is set as the detection surface; and a second output data which are output data of the optical detection system acquired beforehand for each of the first objects in a case in which a surface of an other side opposite to the one side of the first object is set as the detection surface. The processing apparatus matches measurement data with the database, the measurement data being the output data of the optical detection system which is acquired with respect to a second object, and determines a type of the second object.
