Sensor Structure
First Claim
1. A sensor structure comprising:
- a housing including a connector that mediates an input/output exchange with an outside and a terminal of the connector; and
an electronic circuit board that is mounted inside of the housing and includes a humidity sensing element,the terminal of the connector and the electronic circuit board being electrically connected to each other,the sensor structure being inserted to be attached to an airflow tube through which a main air flows, via a seal material provided in the housing, whereinthe housing includes a plurality of bypass channels that each communicate an inside of the housing with an inside of the airflow tube, andthe plurality of bypass channels are each provided at an offset point with respect to a flow direction of the main air flowing through the airflow tube, and each have an opening near an inner wall surface of the airflow tube.

Abstract
A sensor structure capable of achieving both resistance to pollution and measurement performance such as humidity responsiveness is disclosed as is a multifunction sensor capable of facilitating integration of detecting devices for various physical quantities. The sensor structure includes a housing including a connector that mediates an input/output exchange with an outside and a terminal of the connector; and an electronic circuit board that is mounted inside of the housing and includes a humidity sensing element, the terminal of the connector and the electronic circuit board being electrically connected to each other, the sensor structure being inserted to be attached to an airflow tube through which a main air flows, via a seal material provided in the housing. The housing includes a plurality of bypass channels that each communicate an inside of the housing with an inside of the airflow tube.
