Broadcom Digital RGB, IR and Ambient Light Sensors

Broadcom Digital RGB, IR, and Ambient Light Sensors convert light intensity to a digital output signal. These sensors use four individual channels of red, green, blue, and IR (RGB+IR) in a specially designed matrix arrangement. This arrangement allows the sensors to have an optimal angular response and accurate RGB spectral response with high lux accuracy over various light sources. These modules support an I²C-bus interface and include a programmable interrupt controller that uses minimal microcontroller (MCU) resources. Broadcom Digital RGB, IR, and Ambient Light Sensors can be used to read the IR content in certain lighting conditions and detect the type of light source using the IR sensing feature. The series also offers a color-sensing feature that is useful in applications such as LED RGB backlight control, solid-state lighting, reflected LED color sampler, and fluorescent light color temperature detection.
