1. A system, comprising:
- lighting devices, each respective lighting device comprising;
(a) a light source;
(b) a sensor coupling, configured to present a sensor connection interface standardized across at least a plurality of the lighting devices, the standardized connection interface being compatible with a plurality of different types of sensors;
(c) a sensor connected to the standardized connection interface of the sensor coupling, the sensor being of one of the types and located so as to sense one of a plurality of conditions external to the respective lighting device not directly related to operational performance of the respective lighting device, the sensor being configured to output a signal responsive to the one sensed condition via the standardized connection interface of the sensor coupling;
(d) a processor coupled to the sensor coupling for processing data responsive to the signal from the sensor;
(e) a memory accessible to the processor;
(f) a program corresponding at least in part to the one type of the sensor, stored in the memory for execution by the processor, for controlling at least one function of the processor responsive to the condition sensed by the sensor; and
(g) a communication interface accessible by the processor, configured to enable the processor to communicate information resulting from the at least one function of the processor responsive to the condition sensed by the sensor through a communications network;
first layer computers having communications interfaces, wherein each first layer computer is configured to communicate through the communications network with a different respective group of the lighting devices so as to receive the information from the processors of the respective group of the lighting devices and is configured to process the received information to obtain resultant information; and
a second layer computer having a communications interface to communicate through a communications network to receive the resultant information from the first layer computers, wherein the second layer computer is configured to initiate at least one action in response to processing of the resultant information received from the first layer computers.
