The invention relates to a hygienic sheet material dispenser (1) comprising a housing (2) with a dispensing opening (3), a compartment (4) for a sheet material product (5), a first sensor (6) arranged to assume an active mode in which it scans for the presence of a user, a dispensing motor (10) arranged to drive a driving mechanism (11,12), a second sensor (7) for sensing when a piece of said product (5) has been removed, and a microcontroller (9) connected to the first sensor (6), the second sensor (7) and the dispensing motor (10), said dispenser (1) also being configured to be switched to a passive mode. The dispenser (1) is arranged to switch to the passive mode after a first predetermined period of time has elapsed in the active mode without detection of a user; wherein, upon entering the passive mode, a length of said product (5) is fed from the dispenser (1) out of the dispensing opening (3) and the first sensor (6) and the microcontroller (9) are substantially deactivated; and wherein the dispenser (1) is arranged to switch back to the active mode when the second sensor (7) senses that said product (5) has been removed. |
