A system for identifying handling events of an item is provided. The system includes at least one wireless sensor node, WSN, tag associable with the item. The WSN tag includes a transceiver and at least one sensor. The at least one sensor is configured to generate sensor data based at least in part on motion of the wireless sensor node. The WSN tag includes a memory configured to store at least one event filter and the sensor data. The WSN tag further includes a tag processor that is configured to filter the sensor data based on the at least one event filter. The tag processor is configured to determine whether an event occurred based on the filtering of the sensor data and generate event data in response to determining an event occurred. The tag processor is configured to cause the transceiver to transmit the event data.
