Abstract: In some implementations, a system may activate sensors of a smart shelf based on detected events. The system may include a first sensor array configured to monitor a surface of the smart shelf. The first sensor array may be associated with a first type of sensor. The system may include a second sensor array configured to monitor the surface of the smart shelf. The second sensor array may be associated with a second type of sensor. The system may include a controller. The controller may receive, from a first sensor of the first sensor array, a first sensor value. The controller may detect an occurrence of an event based on the first sensor value, wherein the event is associated with an item of the smart shelf. The controller may activate one or more second sensors of the second sensor array based on the occurrence of the event.
