Embodiment Construction

[0029] figure 1 A sensor 1 is shown, which is designed, for example, as a pressure sensor.

[0030] The sensor 1 has a sensor element 2 which is arranged in a chamber 3 . Inside the chamber 3 there is a first volume V 1 of air, the first volume partially surrounds the sensor element 2 . In particular, the sensor element 2 extends laterally and upwardly from the first volume V 1 surrounded. first volume V 1 The connection to the exterior space 5 is via a tubular air supply 4 . The sensor 1 has an open structure so that air and water can enter the air supply device 4 from the outside.

[0031] Chamber 3 is partially delimited by housing 6 . The housing 6 has an opening 7 through which the air supply device 4 is guided. In the illustrated embodiment, the air conveying device 4 is partially introduced into the opening 7 . For example, the air supply device 4 can also be completely inserted into the opening 7 or be connected externally to the opening 7 . Laterally, the ch...

Abstract

The invention relates to a sensor (1) comprising a chamber (3) with a sensor element (2) arranged therein, the chamber (3) comprising a first volume (V1) of air. The sensor (1) has a tubular air supply (4) to the chamber (3), wherein the air supply (4) has a second volume (V2) of air and a penetration of water through the air supply (4) to the sensor element (2) is prevented by the dimensions of the air supply (4), which define the second volume (V2).

Description

technical field [0001] A sensor is proposed, in particular an environmental sensor. Background technique [0002] Sensors, especially environmental sensors, are increasingly used in the field of portable consumer electronics, such as in mobile phones, watches and wristbands. Especially when used in the field of sports it is desirable for the sensor to be waterproof. [0003] Patent documents US 6,754,137 B1, US 5,500,835 A, DE 10 2006 056 128 B4 and EP 0640 896 B1 each describe a watch with a pressure sensor. In order to prevent water from entering the sensor element, the sensor element can be surrounded by a hydrophobic gel or separated from the ambient air by a membrane. A pressure sensor for vehicles is known from patent application DE 10 2006 040 665 A1, in which the penetration of water into the housing of the sensor is prevented by a water-tight filter. Such sensors generally have large overall dimensions and / or are expensive to produce. Contents of the invention ...
