Abstract
A sensor module includes a light emitter that emits light beams including near-infrared light beams towards a subject; a light receiver that receives light beams having passed through the subject; and a controller that estimates biological information based on signals output from the light receiver. The light emitter includes a plurality of light emitting elements that emit near-infrared light beams having central wavelengths different from each other. The light emitter produces sets of light emissions by causing the plurality of light emitting elements to sequentially and intermittently emit the near-infrared light beams. In given two consecutive sets of light emissions produced by the light emitter, a second non-light-emission period of time Tis longer than a first non-light-emission period of time TThe controller estimates the biological information in a processing period of time Tthat is set in correspondence with the second non-light-emission period of time T
