This Light Dependant Resistor (LDR) can be used to easily measure ambient light with your Arduino or other board with analog input. You will need to set this up as a voltage divider with a resistor of around 10KΩ. ...

SKU: LB-LS2299 | Brand: Little Bird

A UV detection sensor module that measures ultraviolet light intensity in the 200–370 nm wavelength range. The analogue output (0–1 V DC) is proportional to the UV Index, making it suitable for measuring UV exposure i...

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ. To use, connect one side o...
