Abstract: A housing defines a bypass passage and a sub-bypass passage. The bypass passage draws a part of air flowing through an interior of a duct. The sub-bypass passage is branched from the bypass passage to draw a part of air flowing through the bypass passage. A flow sensor is equipped in the sub-bypass passage to cause heat transfer with air, which passes through the sub-bypass passage, and to generate an electric signal according to a flow quantity of air in the duct. An intake-air temperature sensor is configured to measure a temperature in the duct. A moisture sensor is configured to measure a humidity in the duct. The flow sensor and the multiple sensors are equipped in the sub-bypass passage and are located along a direction of flow of air in the sub-bypass passage.

Abstract: A housing defines a bypass passage and a sub-bypass passage therein. A bypass passage is configured to draw a part of an air flowing through a duct. The sub-bypass passage branches off the bypass passage and is configured to draw a part of air flowing through the bypass passage. A flow rate sensor is arranged in the sub-bypass passage and configured to generate an electric signal according to a flow rate of air in the duct by performing heat transfer with air passing through the sub-bypass passage. A physical quantity sensor is configured to measure a physical quantity of air in the duct. A sensor assembly is integrally formed with the flow rate sensor, the physical quantity sensor, and a circuit module. The circuit module includes a substrate that is configured to process signals from the flow rate sensor and the physical quantity sensor.

Abstract: An intake device includes an air filter that filters intake air for an internal combustion engine, a filter casing housing the air filter, and an air physical quantity sensor. The filter casing includes an intake passage to allow the intake air to pass from upstream to downstream of the air filter. The filter casing has a passage wall portion that is electrically conductive and exposed to the intake passage on a downstream side of the air filter. The air physical quantity sensor has: a sensor element that detects a specific physical quantity related to the intake air on a downstream side of the air filter; and a grounding structure electrically connected to the passage wall portion for grounding the sensor element.
