Abstract:
A particulate matter (PM) sensor comprises a substrate forming a cavity (5), the substrate comprising a semiconductor chip (4), and a light source (1) arranged in the cavity (5). The light source (1) is adapted to emit a light beam (7). The light beam (7) forms a detection volume (8) for particulate matter (9) outside the cavity (5). Optionally, the particulate matter sensor comprises an optical element (2) delimiting the cavity (5) at one end. The optical element (2) is configured to shape the light beam (7). Further, the particulate matter sensor comprises at least one photodetector (3) that is integrated into a surface of the semiconductor chip (4). The surface into which the at least one photodetector (3) is integrated faces the detection volume (8). The at least one photodetector (3) is adapted to detect light (10) scattered by particulate matter (9) in the detection volume (8).
Abstract:
An electronic component comprises a carrier (3), a sensor device (2) mounted on the carrier (3), which sensor device (2) comprises a sensor chip (21), and an electrostatic discharge protection element (1) for protecting the sensor chip (21) from an electrostatic discharge, which protection element (1) is mounted on the carrier ( 3).
Abstract:
A sensor device (10) comprises an environmental sensor (22) for determining an environmental parameter associated with a sensor gas flow (F2) through the sensor device. The environmental sensor may be a particulate matter sensor for detecting particulate matter in the sensor gas flow. The sensor gas flow is preheated upstream of the environmental sensor (22). To this end, waste heat generated by the environmental sensor (22) itself and/or by a different sensor (12) that is comprised in the sensor device is used. In this manner, the effects of evaporable droplets in the sensor gas flow (F2), as typically present in fog, may be reduced. In some embodiments, a fog signal is derived.
Abstract:
The invention relates to a sensor module (1), comprising: at least a first sensor (10) that is designed to measure relative humidity and/or temperature, wherein the sensor module (1) is configured to be mounted in an automotive seat (2), which automotive seat (2) comprises a seat cover region (200) forming an outer surface (200a) of the seat that faces a passenger (P) sitting on the automotive seat (2), wherein the sensor module (1) is configured to be mounted such in said automotive seat (2) that it is spaced apart from said seat cover region (200). Further, the invention relates to an automotive seat (2) comprising such a sensor module (1).
