Activity tracking using motion sensors in a wireless luminaire network

A system, comprising:

• a plurality of nodes located within a space, each node comprising:
• a node network communication interface, connected to a system network;
• a motion sensor, configured to sense motion in a respective node sensing area;
• a node processor coupled to control the motion sensor and coupled to communicate via the node network communication interface;
• a node memory coupled to the node processor, configured to store a plurality of motion sensing records created by the node processor;
• and
• node programming in the node memory, wherein execution of the node programming by the node processor of a respective node configures the respective node to implement functions, including functions to:
• create a respective motion sensing record, based on motion sensed in the respective node sensing area by the motion sensor, over the system network via the node processor of the respective node;
• store in the node memory of the respective node the respective motion sensing record;
• and
• send, via the node network communication interface of the respective node, the respective motion sensing record over the system network;
• a motion mapping server comprising:
• a motion mapping server processor;
• a motion mapping server network communication interface coupled to the motion mapping server processor, connected to the system network;
• a motion mapping server memory coupled to the server processor, configured to store the motion sensing record sent by the respective node;
• and
• motion mapping programming in the server memory, wherein execution of the motion mapping programming by the motion mapping server processor configures the motion mapping server to implement functions, including functions to:
• receive, via the system network, the respective motion sensing record of the respective node;
• determine, over an aggregated period of time, an aggregated time node motion amount detected in the respective node sensing area of the respective node, by compiling the plurality of motion sensing records from the respective node created by the respective node during the aggregated period of time;
• determine, at an aggregated point in time, an aggregated space node motion amount detected in the node sensing areas of a subset or all of the nodes, by compiling the plurality of sensing records from the subset or all of the nodes created by the subset or all of the nodes at a time substantially close to the aggregated point in time;
• compute a temporal aggregated motion amount detected in the node sensing area of the respective node over time, using the aggregated time node motion amount;
• and
• compute a spatial aggregated motion amount in a portion of the space, using the aggregated space node motion amount where the portion of the space correlates to the node sensing areas of the plurality of nodes.
