1. A patient monitoring system comprising:
a plurality of sensor systems each comprising:
a voiding sensor comprising an electrical circuit configured to be transitioned from a first impedance state to a second impedance state in response to a voiding event in an absorbent region of an absorbent article wearable by a corresponding patient, wherein the electrical circuit is either open or closed in the first impedance state and the other of open or closed in the second impedance state;
one or more motion sensors configured to generate motion data indicative of motion of the patient;
a first communication module; and
one or more first processors configured to:
determine, based on whether the impedance state of the electrical circuit is open or closed, that the voiding event has occurred,
generate, based at least in part on the occurrence of the voiding event, first patient status data of the patient,
cause the communication module to transmit, via at least one relay module and to a remote monitoring device distinct from the at least one relay module, the first patient status data,
determine, based at least in part on the motion data, patient motion or posture state,
generate, based at least in part on the patient motion or posture state, second patient status data, and
responsive to determining that a current time is within a predetermined time of day, cause the communication module to transmit, via the at least one relay module and to the remote monitoring device, the second patient status data; and
the remote monitoring device, comprising:
a second communication module configured to receive a plurality of first patient status data and a plurality of second patient status data from the plurality of sensor systems;
one or more second processors configured to:
generate one or more notifications based on one or more of the plurality of first patient status data and the plurality of second patient status data; and
present the one or more notifications to a caregiver.
