1. A sensor system for detecting a property of or within an absorbent article, comprising:

  • an absorbent article comprising a front region, a back region, and a crotch region, a transverse axis and a longitudinal axis;

    the absorbent article further comprising an elongate housing comprising a first sensor and a second sensor;

    a first transmitter;

    wherein the elongate housing is disposed such that each of the first and second sensors are disposed forward of the transverse axis of the absorbent article;

    wherein no sensor of the sensor system and no portion of the housing is disposed rearward of the transverse axis;

    wherein at least one of the first and second sensors overlaps with the longitudinal axis;

    wherein the elongate housing is disposed along a longitudinal axis of the absorbent article, and wherein the elongate carrier layer is disposed on a garment-facing, exterior surface of the absorbent article, and wherein the elongate housing comprises at least one of hooks and loops;

    wherein the first sensor has a first status and is capable of changing to a second status;

    wherein the second sensor has a third status and is capable of changing to a fourth status;

    wherein at least one of the first and second sensors are capable of sensing a color change through the garment-facing, exterior surface of the absorbent article;

    wherein the first transmitter is capable of transmitting a signal when a change in status of the first sensor from the first status to the second status has occurred;

    wherein the first transmitter is capable of transmitting a signal when a change in status of the second sensor from the third status to the fourth status has occurred;

    wherein the first transmitter is capable of operating at a first power level during an assessment operation and a second power level, higher than the first power level, during a transmission operation; and

    wherein the first transmitter emits an average of less than 1 mW/cm2 per hour, and wherein the first transmitter emits non-continuously when signaling to a remote device.
