Abstract
A luminaire comprising: at least one light source arranged to emit light to illuminate an outdoor environment of the luminaire; at least one sensor, each of the at least one sensor arranged to provide a sensor output signal; a control module arranged to receive the sensor output signal from each of the at least one sensor and configured to communicate with a component of the luminaire based on the at least one sensor output signal; and a precipitation detection module arranged to receive the at least one sensor output signal and configured to detect occurrence of precipitation in the outdoor environment based on the at least one sensor output signal and control the light emitted from the at least one light source based on said detection.
Claims14
A luminaire comprising:
- at least one light source arranged to emit light to illuminate an outdoor environment of the luminaire;
- at least one sensor, each of the at least one sensor integrated into the luminaire and arranged to provide a sensor output signal;
- a control module arranged to receive the sensor output signal from each of the at least one sensor and configured to communicate with a component of the luminaire based on the at least one sensor output signal;
- a memory storing reference precipitation information;
- and
- a precipitation detection module configured to receive the at least one sensor output signal from each of the at least one sensor,
- wherein the precipitation detection module is configured to convert the at least one sensor output signal into a frequency domain waveform and compare the frequency domain waveform to the reference precipitation information,
- wherein the precipitation detection module is configured to detect precipitation in the outdoor environment based on said comparison,
- wherein the precipitation detection module is configured to control the light emitted from the at least one light source based on said detection.
A mobile device comprising:
- output means;
- at least one sensor, each of the at least one sensor integrated into the mobile device and arranged to provide a sensor output signal;
- a control module arranged to receive the sensor output signal from each of the at least one sensor and configured to communicate with a component of the mobile device based on the at least one sensor output signal;
- a memory storing reference precipitation information;
- and
- a precipitation detection module configured to receive the at least one sensor output signal from the each of the at least one sensor,
- wherein the precipitation detection module is configured to convert the at least one sensor output signal into a frequency domain waveform and compare the frequency domain waveform to the reference precipitation information,
- wherein the precipitation detection module is configured to detect precipitation in the outdoor environment based on said comparison,
- wherein the precipitation detection module is configured to control the output means to provide an output signal based on said detection.
