    摘要: The invention relates to an inclination sensor having a level that has a liquid and a gas bubble under a covering glass in a housing. A light source is arranged above the covering glass. The invention is based on the object of providing an inclination sensor, which can be used to determine the direction and degree of an inclination with high accuracy and which is suitable for automatically aligning an apparatus provided with said inclination sensor. The object is achieved according to the invention by an arrangement in which at least two light receivers (2.4) are arranged above the covering glass (1.3) such that the light (L) that is emitted from the light source (2.3) and, in the case of a centered gas bubble (4), is scattered on the surface of the covering glass (1.3) coming in contact with the gas bubble (4) can be detected by means of said at least two light receivers (2.4). Different quantities of light can be detected by means of said light receivers (2.4) when the gas bubble (4) is not centered, and the light source (2.3) and the light receivers (2.4) are arranged on a chip substrate (2.1).
