5. The method of claim 4 , further comprising determining, by the light powered wireless device, the state of the room based at least on the state of motion for the room.
6. The method of claim 1 , wherein (a) further comprises detecting, by the light powered wireless device, one or more nearby devices based on scanning for wireless signals.
7. The method of claim 6 , further comprises determining, by the light powered wireless device, the state of the room based on one or more of the following: whether or not a nearby device is in the room and a status of the one or more nearby devices.
8. The method of claim 1 , wherein (b) further comprises broadcasting, by the light powered wireless device, a plurality of beacons with payloads comprising a unique identifier of the light powered wireless device.
9. The method of claim 1 , wherein information on the state of occupancy of the room comprises information identifying at least one of whether the room is occupied, how many occupants located in the room or an identity of one or more occupants in the room.
10. The method of claim 1 , wherein (c) further comprises transmitting, by the one or more mobile devices, to the server an identifier of the light powered wireless device.
11. The method of claim 1 , wherein (c) further comprises transmitting, by a mobile device of the one or more mobile devices, to the server location information identifying that the mobile device is one of nearby the light powered wireless device of the room or in the room.
12. A system comprising:
a light powered wireless device positioned in a room near a light source, the light powered wireless device comprising:
a solar power module comprising at least one solar cell configured to detect light from the light source;
a microphone configured to detect sound; and
a processor configured to identify a state of the room based on at least a state of the light source responsive to the solar power module measuring a voltage of the at least one solar cell;
one or more mobile devices nearby the room configured to receive one or more beacons transmitted from the light powered wireless device, wherein a payload of the one or more beacons comprises information indicating the state of the room determined by the light powered wireless device based at least on the measurement of voltage of the at least one solar cell; and
a server configured to identify in a database that a state of occupancy of the room is occupied or unoccupied based on at least the information indicating the state of the room determined by the light powered wireless device based at least on the measurement of voltage of the at least one solar cell received from the one or more mobile devices.
13. The system of claim 12 , wherein the processor of the light powered wireless device is further configured to determine that the state of the light source is on or off based on the measurement of voltage of the at least one solar cell of the light powered wireless device.
14. The system of claim 12 , wherein the processor of the light powered wireless device is further configured to determine the state of the room based on a state of sound determined based on whether the microphone of the light powered wireless device detects ambient sound.
15. The system of claim 12 , wherein the processor of the light powered wireless device is further configured to determine a state of motion for the room based on whether a sensor of the light powered wireless device detects movement in the room.
16. The system of claim 15 , wherein the processor of the light powered wireless device is further configured to determine the state of the room based at least on the state of motion for the room.
