According to an aspect, a detection device includes: an optical sensor comprising photodetection elements arranged in a planar configuration; a light source configured to emit light to the photodetection elements; and an object placement member. The light source, the object placement member, and the optical sensor are arranged in the order as listed. The optical sensor is configured to obtain baseline data in an initial state after power-on. The detection device is configured to: obtain difference data based on a difference between the baseline data and sensor values obtained from the photodetection elements at intervals of a predetermined period of time; and output, when the difference data has exceeded a first threshold, either an alert indicating detection of the objects to be detected in an initial moisture region indicating presence of moisture in the initial state, or an alert indicating detection of the objects to be detected.
