Light, Color sensors at affordable cost - Xbotics
The resistance of 20mm GL20528 Light Sensitive Photoresistor LDR changes with the change in the ambient light exposed on the surface of the sensor. As the light on the sensor increases then the resistance across the two leads decreases.
The TCS3200 Color Recognition Sensor Module uses a high-quality light sensor allowing you to sense any color through a combination of Red, Green, and Blue. The module provides all of the pins of the TCS3200 on convenient 0.1″ headers – ideal for use with PCBs, breadboard or stripboard.
This is GYML8511 Analog Output Ultra-Violet Light Sensor Module. The GYML8511 module is easy to use the ultraviolet light sensor. The GYML8511 Sensor works by outputting an analog signal in relation to the amount of detected UV light.
