1. A sensor for measuring a signal indicative of at least one physiological parameter of tissue, the sensor comprising:
a circuit comprising an emitter and a detector;
a sensor housing configured to enclose at least part of a finger, the sensor housing extending beyond a tip of the finger when the at least part of the finger is enclosed by the housing, the sensor housing further enclosing the emitter and the detector, the emitter and detector arranged such that light emitted from the emitter in operation passes through the at least part of the finger before being received by the detector;
an electrical conductor extending through a body of the sensor housing and providing a connection between the emitter and the detector; and
wherein the sensor housing includes an opening, wherein the opening is filled in with a light pipe so as to protect the emitter while allowing at least some of a light emitted by the emitter to be visible external to the sensor housing.
