Abstract

Disclosed is a system for controlling growth of microorganisms, comprising a first light source (104, 204) for radiating a blue light at a first wavelength that ranges between 400 to 480 nanometres to control growth of microorganisms; a second light source (106, 206) for radiating an ultraviolet light at a second wavelength that ranges between 250 to 300 nanometres to kill microorganisms; a light sensor (110, 212) for detecting an intensity of a light; a motion sensor (112, 214, 306, 406) for detecting a moving object (408); and a microcontroller (108), communicatively connected to the first light source, the second light source, the light sensor and the motion sensor, configured to modify an intensity of the blue light based on the light sensor data; and control an intensity of the ultra-violet light based on detection of a moving object by the motion sensor.
