Abstract

The invention relates to a sensor board comprising a plate-like body comprising a body material and having two surfaces substantially parallel to each other, and at least one optical sensor and at least one non-optical sensor, the sensors being positioned at the same surface of the body, wherein the body includes a first area having a thickness D₁ of the body material and a second area having a thickness D₂ of the body material, where D₁>D₂>0, the at least one optical sensor being positioned at the second area.
