Abstract: A sensor unit (1) comprises at least one sensor (3) that is arranged on a circuit board (2) and a cover (4) for the sensor (3). The cover (4) is open toward the circuit board (2) and adjoins the circuit board (2) in the installed state. The underside (14) of the circuit board simultaneously forms part of the seal. The at least one sensor (3) is completely climate-encapsulated.

Abstract: A sensor means is proposed to determine an interior humidity and/or an interior volume delimited by a wall, in particular, of a vehicle passenger compartment 3, and a fogging up tendency of an inner surface of the wall, in particular, of a window 5 of the vehicle passenger compartment 3, with a dew point sensor 10 having a humidity sensor element 1 and a temperature sensor 2, wherein the humidity sensor element 1 and the temperature sensor 2 a thermally coupled, and a surface temperature sensor 4, wherein the dew point sensor 10 is designed to measure the air humidity and the room temperature of the interior volume and the surface temperature sensor 4 is designed to measure the temperature of the inner surface.

Abstract: An optical sensor includes a light transmitter for transmitting pulsed light signals and a light receiver for receiving them. In order to suppress the effects of interfering noise light, the light signals are transmitted according to a specified pattern including pulses in packages separated from each other by a specified interval, the pulses within each of the packages following one another with a specified carrier frequency. Groups each including two or more such pulse packages may be employed. The light receiver converts a received light signal into an electrical signal and directly thereafter passes the electrical signal through a bandpass filter with a pass band including this carrier frequency.
