    Abstract: According to an aspect, a sensor system includes: a first device including a first controller and a first communicator; and a plurality of second devices each including an altitude sensor, a blood oxygen saturation level sensor, a second controller, and a second communicator. The second controller of the second device is configured to transmit altitude information measured by the altitude sensor and biometric information measured by the blood oxygen saturation level sensor to the first device through the second communicator. The first device has determination information comprising determination thresholds for a blood oxygen saturation level corresponding to different altitudes. The first controller is configured to warn that the blood oxygen saturation level is lower than the determination threshold corresponding to the altitude information based on the altitude information and the biometric information received from each of the second devices through the first communicator and the determination information.

    Abstract: According to an aspect, a detection device includes: a plurality of light-receiving elements configured to receive light; and a light guide portion one surface of which faces the light-receiving elements. The light guide portion includes a plurality of light guide paths provided throughout from the one surface to the other surface of the light guide portion, and a light-absorbing portion having higher absorbance of the light than that of the light guide paths. When viewed from a direction in which the light-receiving elements and the light guide portion are stacked, more than one of the light guide paths overlap one of the light-receiving elements.

    Abstract: According to an aspect, a detection device includes a pattern detector, a force detector, and a controller. The controller is configured to store reference data in advance, acquire new data, and determine whether an object pressed against a contact surface when the new data is acquired is a human finger based on difference between acquisition target data indicated by the reference data at a plurality of timings and the acquisition target data indicated by the new data at a plurality of timings. The timings are two timings or more that are included in a pressing operation period from start to end of pressing of an external object against the contact surface, and the force detected by the force detector is different between the timings.
