1. A wearable environmental sensor device, the device comprising:
a housing comprising a wall exposed to an environment;
an environmental sensor disposed on the wall and configured to measure ambient environmental information around a living body; and
a protective structure disposed around the environmental sensor, the protective structure comprising first ventilation holes provided in each of two or more pairs of opposed surfaces of the protective structure, wherein, when the wearable environmental sensor device is attached to the living body and the living body is in a standing posture, each of the two or more pairs of opposed surfaces faces in a direction other than a vertical direction of the living body and the wall faces substantially downward from the living body, the two or more pairs of opposed surfaces include a first surface facing the living body, and a second surface facing the first surface, and the first surface with the first ventilation hole is inclined so as to downwardly go further away from the living body.
