A system adapted to identify and react to proximity events is described. The system includes: a set of sensors, each sensor in the set adapted to transmit a wireless beacon signal, the beacon signal including a sensor ID associated with the sensor; at least one mobile device adapted to receive the wireless beacon signal from the sensor and provide a location of the mobile device; and a server adapted to receive the location of the mobile device and the sensor ID, generate instructions based at least partly on the received information, and send the instructions to the mobile device.
