Wavelength sensing lighting system and associated methods
A lighting system comprising a light source operable to emit a source light, a sensor operable to sense environmental light from an environment, and a controller operatively connected to each of the sensor and the light source and configured to analyze the environmental light sensed by the sensor to at least one of detect and generate data relating to a condition of the environment, the data being transmittable in a transmitted data light. The sensor is operable to sense the presence or absence of a dominant wavelength comprised by the environmental light. Additionally, the controller is operable to correlate the dominant wavelength with a substance.
