Retail item management using wireless sensor networks

A system for identifying handling events of an item, the system comprising:

• at least one wireless sensor node, WSN, tag associable with the item, the WSN tag comprising:
• a transceiver;
• at least one sensor, the at least one sensor configured to generate sensor data based at least in part on motion of the WSN tag;
• a memory, the memory configured to store at least one event filter and the sensor data;
• a tag processor, the tag processor configured to:
• filter the sensor data based on one of the at least one event filters, the one of the at least one event filters defining a plurality of movements and a threshold, each of the plurality of movements having to meet the threshold for the one of the least one event filters to be met;
• determine whether an event occurred based on the filtering of the sensor data;
• generate event data in response to determining an event occurred;
• and
• cause the transceiver to transmit the event data.
