Abstract
The present invention relates to data logger units, sensor units, and in particular those which are suitable for sensing the hygienic state of an absorbent article. The present disclosure also relates to a method of identifying a sensor unit for an absorbent article performed by a data logger unit adapted to cooperate with the sensor unit, as well as an absorbent article management system. The data logger unit and the sensor have identification terminals. A characteristic property of the sensor unit is encoded in the potentials at each of the identification terminals. The data logger unit can decode the potentials at each of the identification terminals to determine the characteristic property of a connected sensor unit.
