Abstract

Sensor for determining measured variables which are suitable for controlling an air-conditioning system and other apparatuses which influence the climate of an area, including a motor vehicle, has a single sensor housing and a printed circuit board which is equipped with sensor elements for determining the measured variables and with electronic components for processing electrical signals produced by the sensor elements, as a function of the measured variables. In the sensor, at least one light-sensitive sensor element and one gas-sensitive sensor element are arranged in the single sensor housing.

Claims

1-7. -7. (canceled)

8. A sensor (1) for determining measured variables which are suitable for controlling an air-conditioning system (21) and other apparatuses (19, 20, 22, 23) which influence the climate of an area, being suitable for arrangement in a motor vehicle, the sensor comprising:

a single sensor housing (13), and a printed circuit board (10) which is equipped with sensor elements (2, 5, 7, 24) for determining the measured variables;

wherein the printed circuit board has electronic components (9) for processing electrical signals outputted by the sensor elements (2, 5, 7, 24), as a function of the measured variables;

wherein at least one light-sensitive sensor element (2) and one gas-sensitive sensor element (5) are arranged in the one single sensor housing (13).

9. The sensor (1) as claimed in claim 8, wherein a moisture-sensitive sensor element (7) is additionally arranged in the single sensor housing (13).

10. The sensor (1) as claimed in claim 8, wherein a temperature-sensitive sensor element (24) is additionally arranged in the single sensor housing (13).

11. The sensor (1) as claimed in claim 8, wherein the printed circuit board (10) is in the form of a flexible printed circuit board.

12. The sensor (1) as claimed in claim 8, wherein the printed circuit board (10) is in the form of a punched metal part.

13. The sensor (1) as claimed in claim 8, wherein the electronic components (9), which are arranged on the printed circuit board (10) in the sensor housing (13), process the electronic signals produced by the sensor elements (2, 5, 7, 24) to such an extent that the at least one connected controller (18), which is supplied with information by the sensor (1), requires a relatively low computational power and a relatively low storage capacity.

14. The sensor (1) as claimed in claim 8, wherein the electronic components (9), which are arranged on the printed circuit board (10) in the sensor housing (13), process the electronic signals produced by the sensor elements (2, 5, 7, 24) to such an extent that said signals are available in the form of standardized signals to downstream electronics.
