Abstract: A rain sensor equipped to a transparent substrate includes a light emitter emitting irradiation lights toward the transparent substrate, light receivers receiving reflected lights of the irradiation lights being reflected on the transparent substrate, a defining section defining an incident angle of each reflected light with respect to each light receiver, and a detection section detecting rainfall amount based on signals output from the light receivers. The light emitter emits the irradiation lights toward an irradiation region defined on the transparent substrate. The irradiation region is divided into multiple detection regions. The detection regions correspond to respective light receivers. The defining section defines the incident angle of each reflected light reflected on the detection region such that each reflected light enters corresponding light receiver. The detection section detects the rainfall amount based on the signals output from the light receivers corresponding to the irradiation regions.

Abstract: An adhering matter determination portion includes an irradiation portion, a light receiving portion and a determination portion. The irradiation portion radiates a light to a plurality of different areas of a transparent plate. The light receiving portion converts reflected waves reflected at the different areas into electrical signals. The determination portion compares at least one of detection signals outputted from the light receiving portion with a determination threshold. When the detection signal is lower than the determination threshold, the determination portion determines that there is an adhering matter on the transparent plate. The determination portion compares the detection signals. When a difference of the detection signals is higher than a condensation determination value, the determination portion determines that the adhering matter is raindrops. When the difference of the detection signals is lower than the condensation determination value, the determination portion determines that the adhering matter is dewdrops.

Abstract: A sensor device includes a sensor element detecting a temperature of an attachment member to which the sensor device is attached. The sensor device includes a flexible substrate that includes a base having a first surface and a second surface and made of an electrically insulating material, and a land disposed adjacent to the first surface and electrically connected to the sensor element. The sensor device further includes: a rigid member adhered to the second surface; a flexible member that has a thermal conductivity and a flexibility higher than those of the base, is stacked on the rigid member to be in contact with the rigid member on a side opposite to the flexible substrate, and is to be in contact with the attachment member in an attached state; and a pressing member that presses the flexible substrate toward the attachment member in the attached state.
