Sensor device
A multi-sensor device may perform an optical measurement using an optical sensor of the multi-sensor device, where the optical measurement is performed when a surface of the multi-sensor device is in contact with a human body. The multi-sensor device may perform another measurement using at least one other sensor of the multi-sensor device, where the other measurement is performed when the surface of the multi-sensor device is in contact with the human body, where the other measurement is performed substantially contemporaneously with the optical measurement, and where the optical measurement and the other measurement relate to health parameters. The multi-sensor device may determine a combined measurement value based on the optical measurement and the other measurement.
