BH1750 is a digital Ambient Light Sensor IC with an I2C bus interface. The module does all of the hard work, providing a simple digital value via I2C that represents luminance (Lux).

This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it...

This diode-transistor photocouplers consist of an LED, optically coupled to a high speed photodetector to transmit electrical signals between circuits while still...

This photodiode is made out of environment-friendly materials(no Cadmium and Lead) compared with the traditional CDS photoresistor. It can be used to generate a current when light hits the body of the diode. Depending on your project, this can be easier to work with than a photoresistor.

BH1750FVI is a digital Ambient Light Sensor IC for I2 Cbus interface. This IC is the suitable for obtaining the ambient light data for adjusting LCD and Keypad backlight power of Mobile phone. It is possible to detect wide range at high resolution.

The VCNL4040 is a handy two-in-one sensor, with a proximity sensor that works from 0 to 200mm (about 7.5 inches) and light sensor with range of 0.0125 to 6553 lux...

This T-Slot Photo Interrupter is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped gap. You can control...

The BPW34 is a tiny, general purpose PiN photodiode. This photodiode has a ton of uses, one of which is to use it is a mini solar cell to power your project. The cell is sensitive to a wide range of light wavelengths (430-1100nm), so it should produce power in a number of different settings. The rated open circuit voltage is 350mV (900nm, 1mW/cm2 light source), and short circuit current is 47μA.
