User interface with integrated sensor

A user interface of a respiratory therapy system includes a strap assembly, a frame, a connector, and a sensor. The strap assembly is positioned around the head of the user when the user wears the user interface. The frame is physically and electrically connected to the strap assembly and defines an aperture. The connector has a first end and a second end. The first end of the connector may be positioned within the aperture of the frame such that the connector is physically and electrically connected to the frame. The sensor is coupled to the strap assembly or the frame such that when the user wears the user interface, the sensor abuts a target area of the user. 呼吸治疗系统的用户接口包括绑带组件、框架、连接器和传感器。当用户佩戴用户接口时，绑带组件围绕用户的头部定位。框架物理地且电气地连接至绑带组件，并限定孔口。连接器具有第一端部和第二端部。连接器的第一端部可以定位在框架的孔口内，使得连接器物理地且电气地连接至框架。传感器联接至绑带组件或框架，使得当用户佩戴用户接口时，传感器邻接用户的目标区域。
