Abstract

A resistance measurement method for a vaporizer includes: reading a resistance value of the vaporizer every first preset time to obtain a first preset number of first resistance values; starting the vaporizer and lasting for a second preset time; reading the resistance value of the vaporizer every third preset time to obtain a second preset number of second resistance values; and calculating an average of the first resistance value and the second resistance value as an initial resistance value of the vaporizer.
