A wearable sensor includes: a base member that has a through hole serving as a flow path of liquid and a recess connecting with an end portion of the through hole on an outlet side; a water absorbing structure disposed on a surface of the base member on the outlet side to come into contact with the liquid flowing into the recess from an opening of the through hole on the outlet side; a laser diode that radiates light toward the liquid flowing into the recess from the opening of the through hole on the outlet side; and a photodiode that receives light from the laser diode transmitted through the liquid or light reflected by the liquid. An amount of perspiration of a wearer of the wearable sensor is calculated based on light receiving characteristics of the photodiode.

When a data signal of a first channel is an RZ signal having a pulse period Tand a logic '1' pulse width m, a data signal of a second channel is an RZ signal having a pulse period Tand a logic '1' pulse width n and the relation n&#x3c;m is satisfied, a multiplexed signal D obtained by time-division multiplexing the data signals of two channels is input. A pulse signal with a pulse width k satisfying n&#x3c;k&#x3c;min(m, T) is generated at timing of a leading edge of the data signal of each channel. When the multiplexed signal D is judged as logic &#x201c;1&#x201d; at timing of a trailing edge of the pulse signal, the data signal of the first channel is output. Similarly, when the multiplexed signal D is judged as logic &#x201c;0&#x201d;, the data signal of the second channel is output.
