Colour sensor detects red, green, blue and white light

Mouser now stocks the Vishay VEML6040 RGBW colour sensor which detects red, green, blue and white light. The VEML6040 incorporates photodiodes, amplifiers and analog / digital circuits into a single chip using the CMOS process. Typical applications include handheld devices, notebooks, consumer devices and diverse industrial and mechanical systems. With Filtron technology, the device achieves the closest ambient light spectral sensitivity to human eye responses. When the sensor is applied, brightness and backlight colour temperature can be adjusted based on the ambient light source. The VEML6040 provides excellent temperature compensation capability for keeping the output stable under changing temperature. Its function is easily operated via the simple command format of I2C (SMBus compatible) interface protocol. VEML6040's operating voltage ranges from 2.5V to 3.6V. It is packaged in a lead (Pb)-free 4-pin OPLGA package which offers the best market-proven reliability, says the company.
