 the puff sensor includes a pressure sensor, and   the controller is further configured to reset a reference value of the pressure sensor.   
     
     
         3 . The aerosol generating device of  claim 1 , further comprising an output unit configured to output information regarding a state of the aerosol generating device, wherein the controller is further configured to control the output unit to display a notification of a reset failure when at least one of the temperature sensor and the puff sensor fails to be reset. 
     
     
         4 . The aerosol generating device of  claim 1 , wherein the controller is further configured to control the heater to start a heating operation according to a predetermined temperature profile when the cigarette is inserted. 
     
     
         5 . An aerosol generating device configured to allow a cigarette to be inserted thereinto and comprising:
 a heater configured to heat the inserted cigarette;   a temperature sensor configured to detect a temperature of the heater;   an insertion detection sensor configured to detect insertion of the cigarette; and   a controller configured to set an operation mode of the aerosol generating device to an ON mode or an OFF mode,   wherein the controller is further configured to reset the insertion detection sensor and the temperature sensor when the heater is not activated in the ON mode.   
     
     
         6 . The aerosol generating device of  claim 5 , wherein the controller is further configured to control the heater to start a heating operation according to a predetermined temperature profile when the insertion detection sensor detects the insertion of the cigarette. 
     
     
         7 . The aerosol generating device of  claim 5 , wherein the controller is further configured to reset the insertion detection sensor and the temperature sensor when the insertion detection sensor does not detect the insertion of the cigarette for a preset period of time. 
     
     
         8 . The aerosol generating device of  claim 5 , further comprising:
 a case including an insertion hole into which the cigarette is inserted;   a cover configured to open and close the insertion hole; and   an opening/closing detection sensor configured to detect whether the insertion hole is opened or closed,   wherein the controller is further configured to set the operation mode of the aerosol generating device to the ON mode or the OFF mode based on a sensing signal from the opening/closing detection sensor.   
     
     
         9 . The aerosol generating device of  claim 8 , wherein the controller is further configured to set the operation mode of the aerosol generating device to the ON mode and activate the insertion detection sensor, when the sensing signal indicates that the insertion hole is opened. 
     
     
         10 . The aerosol generating device of  claim 8 , wherein the controller is further configured to set the operation mode of the aerosol generating device to the OFF mode and deactivate the insertion detection sensor, when the sensing signal indicates that the insertion hole is opened. 
     
     
         11 . A method of controlling an aerosol generating device including a heater configure to heat an inserted cigarette, a temperature sensor configured to detect a temperature of the heater, and an insertion detection sensor configured to detect insertion of the cigarette, the method comprising:
 operating the aerosol generating device in an ON mode;   determining whether or not the heater is activated; and   resetting the insertion detection sensor and the temperature sensor when the heater is not activated.   
     
     
         12 . The method of  claim 11 , further comprising, when the insertion detection sensor detects the insertion of the cigarette, controlling the heater to start a heating operation according to a predetermined temperature profile. 
     
     
         13 . The method of  claim 11 , wherein the resetting is performed based on the insertion of the cigarette being not detected for a preset period of time. 
     
     
         14 . The method of  claim 11 , further comprising:
 determining whether or not an insertion hole for the cigarette is opened or closed; and   setting an operation mode of the aerosol generating device to the ON mode based on the insertion hole being opened.   
     
     
         15 . The method of  claim 11 , further comprising:
 determining whether or not an insertion hole for the cigarette is opened or closed; and   when determining that the insertion hole is closed, setting an operation mode of the aerosol generating device to an OFF mode.
