Light/colour/proximity sensor works through attenuating glass
The proximity detection feature allows a large dynamic range of operations for accurate distance detection. For example, it can be used to enable a mobile phone to detect when the user positions the device close to the ear.
The IR LED sink current is factory-trimmed to provide consistent proximity response without requiring customer calibrations. An internal state machine provides the ability to put the device into a low power state in between proximity and RGBC measurements, providing very low average power consumption.
The colour-sensing feature is useful in applications such as LED RGB backlight control, solid-state lighting, reflected LED colour sampler and fluorescent light colour temperature detection. The integrated IR blocking filter also makes the APDS-9950 an ambient light sensor and colour temperature monitor sensor.
