ALS-AK610P-DF provides ALS (ambient light sensing) detection. ALS approximates the human eye's response to light intensity under different lighting conditions through differences in attenuation materials.
WH3620 is a color-based light-to-digital converter that combines photodiodes, current amplifiers, analog circuits, and digital signal processors.
WH26533 is a low-power, high-sensitivity color light sensor with an I2C interface.
ALS-AK510 is a low-cost visible light sensor with a current output proportional to ambient light level.
