Abstract:
A measurement module that measures force being applied to a man-powered machine includes: a strain sensor that detects strain of a crank of the bicycle configured to transmit force being applied from a user through the crank and one front gear selected among one or more front gears; an MM magnetic sensor that detects the crank passing through a predetermined position; and an MM control part. The MM control part calculates a rotation angle of the crank based on an elapsed time from a time the crank passes through the predetermined position that the sensor has detected, calculates force applied to the crank based on a strain amount of the crank that the strain sensor has detected, associates the rotation angle with the force applied to the crank to calculate distribution of the force applied from the user.
