  • DEALING WITH FOG AND CONTAMINATIONS IN ENVIRONMENTAL SENSOR DEVICES
    Publication number: 20240192121
    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.

  • Pressure sensor
    Patent number: 10712218
    Abstract: A sensor includes a deformable membrane that deflects in response to a stimuli. The sensor further includes a capacitive element coupled to the deformable membrane. The capacitive element is disposed within an enclosed cavity of the sensor. The capacitive element changes capacitance in response to the deformable membrane deflecting. The capacitive element comprises a getter material for collecting gas molecules within the enclosed cavity.

  • Pressure sensor
    Patent number: 9958349
    Abstract: A pressure sensor comprises a deformable membrane deflecting in response to pressure applied, a first stationary electrode, and a second electrode coupled to the deformable membrane, for determining a change in a capacitance between the first and the second electrode in response to the pressure applied. At least one of the first and the second electrode comprises a getter material for collecting gas molecules.
