One biological state collection method, device and system (800) and an electronic equipment (100) are provided. Biological aspect acquisition method includes: the output data for obtaining at least one motion sensor (S210) The duration is collected according to the control of at least one biological aspect of a user of at least output data of at least one motion sensor (S220) Collect at least one biological aspect for collecting the user in the duration at least one biological aspect (S230). According to biological aspect acquisition method, device and system (800) and electronic equipment (100), biological aspect collection duration can be properly controlled, and biological aspect measurement accuracy can be improved.
