Abstract
A patient monitoring sensor having a communication interface, through which the patient monitoring sensor can communicate with a monitor is provided. The patient monitoring sensor includes a light-emitting diode (LED) communicatively coupled to the communication interface and a detector, communicatively coupled to the communication interface, capable of detecting light. The patient monitoring sensor also includes a faraday cage disposed around the detector, wherein the faraday cage includes an aperture configured to limit an amount of light from the LED that the detector is able to detect.
