 wherein the controller is configured to:   count a number of times at which a fall history of the body is stored, and   upon determining that the number of times at which the fall history is stored is greater than or equal to a reference number, control the output unit to output information about fall of the body.   
     
     
         7 . The aerosol-generating device according to  claim 1 , wherein the fall history information comprises at least one of a time at which fall occurred, a fall height, a fall duration, a location at which fall occurred, or an amount of impact. 
     
     
         8 . The aerosol-generating device according to  claim 1 , wherein the power supply comprises:
 a first power supply configured to supply power to at least one of the heater, the controller, or the memory; and   a second power supply configured to supply power to the at least one sensor.
