Embodiment Construction

[0027] Denote the housing of the sensor device 2 with 1 ( figure 2 ). This housing 1 has a receptacle 3 and a cover 4 which are releasably connected to one another. The cover plate 4 is substantially circular and has a perforation 5 in the central region of the formed circle. The receiving part 3 has a circular first receiving area 3' and an elongated second connecting area 3''. For connecting the receiving part 3 and the cover plate 4, three detent connections 6, 6', 6'' and two plug connections 7, 7' are provided. The receiving part 3 has three stop elements of the stop connection 6 , 6 ′, 6 ″, in which two stop elements of the stop connection 6 , 6 ′ Elements are arranged on the elongated connection region 3 ″ at the first end of the connection region 3 ″ which rests on the receiving region 3 ′, and the third stop of the locking connection 6 ″ The moving element is arranged on the circular receiving area 3 ′ on the side opposite the elongated connecting area 3 ″. Furt...

Abstract

The invention relates to a device for acquiring predetermined state variables inside a room, in particular in the interior of a motor vehicle, with at least one temperature sensor and with a humidity sensor, at least regions of which are enclosed by a housing, wherein a first temperature sensor exhibits at least one contact surface for abutting against a perimeter surface bordering the room, and that at least one second temperature sensor is provided inside the housing for acquiring the room temperature. The contact surface is thereby a surface piece of a printed circuit board section of a printed circuit board, which encompasses elastic characteristics, wherein the printed circuit board section encompasses a plurality of surface pieces, which are angled relative to one another, and the temperature sensors are arranged at different surface pieces.

Description

technical field [0001] The invention relates to a device for detecting predetermined state variables in the interior of a space, in particular in the interior of a motor vehicle, having at least one temperature sensor and a humidity sensor, which are at least partially Surrounded by a housing, wherein the first temperature sensor has at least one contact surface for abutting against a limiting surface defining the space and at least one second temperature sensor for detecting the temperature of the space is arranged inside the housing sensor. Background technique [0002] Devices of the aforementioned type comprise specific sensor devices and serve to detect state variables by means of which conclusions can be drawn about the prevailing environmental conditions, for example in a greenhouse or in the interior of a motor vehicle. The state variables, such as temperature or air humidity, are measured here in particular continuously by means of a sensor system inside the room, ...
