Motion sensor based lighting fixture operation
A lighting fixture includes a lighting device, a motion sensor, and a wireless transceiver configured to transmit and receive wireless signals. The lighting fixture further includes a controller communicably coupled to the lighting device, to the motion sensor, and to the transceiver. The controller is configured to adjust a light provided by the lighting device based on a motion detection by the motion sensor and based on a wireless input signal received by the transceiver indicating whether a second motion is detected by a second lighting fixture.

The lighting fixture of claim 2 , wherein the wireless input signal includes a second identification string associated with the second lighting fixture, wherein the controller is configured to control the lighting device based on the wireless input signal if the second identification string is a valid string.
4. The lighting fixture of claim 3 , wherein the identification string matches the valid string.
5. The lighting fixture of claim 1 , wherein a power level of the wireless output signal is adjustable based on a user input to increase a number of lighting fixtures that receive the wireless output signal.
6. The lighting fixture of claim 1 , wherein a power level of the wireless output signal is adjustable based on a user input to reduce a number of lighting fixtures that receive the wireless output signal.
7. The lighting fixture of claim 1 , wherein adjusting the light provided by the lighting device includes turning on the light.
8. The lighting fixture of claim 1 , wherein adjusting the light provided by the lighting device includes increasing an intensity level of the light.
9. The lighting fixture of claim 1 , wherein the controller is further configured to adjust the light provided by the lighting device based on a Bluetooth Low Energy beacon signal received from a mobile device.
10. A lighting network, comprising:
a first lighting fixture comprising a motion sensor, the first lighting fixture configured to:
start emitting a first light or change an intensity level of the first light in response to a detection of a motion by the motion sensor; and
transmit a wireless signal indicating the detection of the motion, wherein the wireless signal is a radiofrequency wireless signal and wherein the wireless signal includes an identification string; and
a second lighting fixture, wherein a range of the wireless signal is adjustable such that the second lighting fixture is located within the range of the wireless signal, wherein the second lighting fixture is configured to receive the wireless signal transmitted by the first lighting fixture and to start emitting a second light or change an intensity level of the second light based on the wireless signal.
11. The lighting network of claim 10 , further comprising a third lighting fixture located inside the range of the wireless signal and wherein the third lighting fixture is configured to receive the wireless signal and to start emitting a third light or change an intensity level of the third light based on the wireless signal.
12. The lighting network of claim 11 , wherein the third lighting fixture is configured to start emitting the third light or change the intensity level of the third light based on the wireless signal if the wireless signal includes a valid identification string.
13. The lighting network of claim 10 , further comprising a third lighting fixture located outside a range of the wireless signal transmitted by the first lighting fixture and inside a range of a second wireless signal transmitted by the second lighting fixture, wherein the second wireless signal indicates a second motion detection by a motion sensor of the second lighting fixture and wherein the third lighting fixture is configured to start emitting a third light or change an intensity level of the third light based on the second wireless signal.
14. The lighting network of claim 13 , wherein the third lighting fixture is configured to start emitting the third light or change the intensity level of the third light based on the second wireless signal if the second wireless signal includes a valid identification string.
15. The lighting network of claim 10 , wherein the second lighting fixture is configured to receive the wireless signal transmitted by the first lighting fixture and to start emitting a second light or change an intensity level of the second light based on the wireless signal if the identification string is a valid identification string.
16. A method of controlling lighting, the method comprising:
detecting a motion by a motion sensor of a lighting fixture;
transmitting, by the lighting fixture, an output wireless signal indicating the detecting of the motion by the motion sensor of the lighting fixture, wherein the output wireless signal includes a first identification string associated with the lighting fixture; and
adjusting, by the lighting fixture, a light provided by the lighting fixture based on the detecting of the motion by the motion sensor of the lighting fixture, wherein the output wireless signal includes an identification string associated with a second lighting fixture, wherein the output wireless signal is a radiofrequency signal.
17. The method of claim 16 , further comprising receiving, by the lighting fixture, an input wireless signal by the lighting fixture.
18. The method of claim 17 , further comprising adjusting the light provided by the lighting fixture based on the input wireless signal if the identification string is a valid identification string.
19. The method of claim 17 , wherein the input wireless signal is a radiofrequency wireless signal.
20. The method of claim 16 , further comprising adjusting a range of the output wireless signal by adjusting a power level of the output wireless signal.
