The Color sensor module base on TCS230 which is a programmable color light-to-frequency converter, it could filter RGB data from source light and convert it to a square wave(50% duty cycle) with frequency directly proportional to light intensity (irradiance).
The UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. This module is based on the sensor UVM-30A, which has a wide spectral range of 200nm-370nm. The module outputs electrical signal which varies with the UV intensity, which gives your...
