IR sensors detect red, green, blue, clear and IR light

The VEML3328 and VEML3328SL sensors sense red, green, blue, clear and IR light by incorporating photodiodes, amplifiers and analogue / digital circuits into a single CMOS chip.

With this sensor, the brightness and colour temperature of a display backlight can be adjusted based on the ambient light source, and it can differentiate indoor from outdoor lighting environments.

The multi-spectrum sensors feature a low 2.6V to 3.6V operation voltage, and a low power consumption I2C interface.

These sensors play important functions in today’s electronics. For example, they are used to maintain consistent true colour and ideal brightness levels on handheld displays as users move between indoor and outdoor environments.

They also automatically adjust LCD backlighting, white balancing and colour cast correction in digital cameras, and they monitor LED colour output in smart lighting and other functions.

The Vishay VEML sensors support low transmittance (dark) lens design and provide 16-bit resolution for each channel (R, G, B, C, and IR). Peak sensitivities include: Red: 610nm, Green: 560nm, Blue: 470nm, Clear: 590nm and IR: 825nm.

The VEML3328 is available in an OPLGA4 package, and the VEML3328SL is offered in an OPLGA4 SV (side view) package.

The VEML3328 is 2.0mm x 1.25mm x 1.0mm and the side looking sensor is 2.95mm x 1.50mm x 1.50mm.

Both devices are Pb-free, halogen free, and RoHS compliant and boast a floor life of 168 hours.
