The invention relates to a method for detecting a liquid discharge event in an absorbent article, wherein said absorbent article comprises a sensor adapted to generate an electrical output signal representative of a degree of wetness of said absorbent article, wherein said electrical output signal is received by a processing unit. The method comprising the steps of providing reference data over time representative of a liquid discharge； acquiring liquid discharge dataover time in form of said electrical output signal； analysing said liquid discharge data over time in relation to said reference data over time by means of said processing unit； and detecting a liquid discharge event based on said analysis. The invention relates also to a system for detecting liquid discharge event in an absorbent article, said system comprising an absorbent article comprising a sensor being arranged to generate an output signal representative of an electrical property, and a processing unit adapted to process said output signal generated by the sensor of the absorbent article. The processing unit is adapted to perform the method according to the invention, and detect a liquid discharge event in said absorbent article based on said method.
