1. A lighting system node comprising:
a sensor board comprising:
a plurality of sensors configured to sense parameters from the environment and to generate sensory outputs; and
a transmission circuit configured to receive sensory output from the plurality of sensors and to generate sensor data for transmission through a wired connection; and
a light driver external to and electrically coupled to the sensor board, and configured to receive the sensor data from the sensor board and to generate a drive signal for powering a light source based on the sensor data, the light driver comprising:
a converter comprising a transformer and configured to generate the drive signal at an output of the transformer for powering the light source based on a control signal;
a modular controller board electrically coupled to the sensor board through the wired connection and configured to receive the sensor data from the sensor board and to generate a first sensor control signal and a second sensor control signal corresponding to the sensor data;
a primary controller configured to control the converter by generating the control signal based on the first sensor control signal; and
an intensity controller coupled to the output of the transformer, the intensity controller being configured to receive the drive signal and to control at least one of a light intensity of the light source and a color shade of the light source in response to the second sensor control signal,
wherein the modular controller board comprises:
a wireless module configured to wirelessly receive an external command from an external controller, and
a processor configured to generate the first and second sensor control signals based on the sensor data and the external command.
