Detecting presence using a presence sensor network

A system comprising:

• a processor;
• and
• a memory that stores computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising
• obtaining sensor identifier data that identifies a presence sensor that is located at a monitored location, the sensor identifier data comprising a first unique identifier associated with the presence sensor and data that defines a location of the presence sensor at the monitored location,
• storing the sensor identifier data,
• obtaining presence data associated with the monitored location, the presence data comprising a plurality of unique identifiers associated with a plurality of presence sensors located at the monitored location,
• comparing the first unique identifier to the presence data, and
• determining that an object is located at the monitored location in response to a determination that the first unique identifier is not included in the presence data.

A computer storage medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

• obtaining sensor identifier data that identifies a presence sensor that is located at a monitored location, the sensor identifier data comprising a first unique identifier associated with the presence sensor and data that defines a location of the presence sensor at the monitored location;
• storing the sensor identifier data;
• obtaining presence data associated with the monitored location, the presence data comprising a plurality of unique identifiers associated with a plurality of presence sensors located at the monitored location;
• comparing the first unique identifier to the presence data;
• and
• determining that an object is located at the monitored location in response to a determination that the first unique identifier is not included in the presence data.
