Wiring the Broadcom APDS 9253 001 Digital RGB IR Light Sensor

The APDS9253 001 is a digital RGB IR Flux Sensor, and an ambient light sensor that converts light intensity to a digital output signal, The APDS9253 sensor uses 4 individual channels of RGB (Red, Green, Blue and Infrared (RGB+IR) suitable for designing a matrix arrangement. Additionally, it allows the device to have an optimal angular response and accurate RGB spectral response with high LUX accuracy over various light sources. This device communicates up to 400kHz using TWI (Two Wire Interface) or i2C protocol interface and integrated programmable interrupt controller that takes minimal resource from the microcontroller.

The color sensing technology is useful in an application such as LED RGB backlight controller, solid-state lightning, reflected LED color sampler, fluorescent light color temperature detection, applicable for Smart Handheld Devices, Detections of ambient light to control display backlighting, wearable devices, computing devices, consumer devices, automatic residential and commercial lighting management, lab instrumentation’s, etc. with the help of IR sensing the device can be used to read the IR content in certain lighting conditions and detect the type of light source.

The APDS9253001 has an advance accuracy of correlated color temperature (CCT) with approximate human eye response with a green channel and low light sensitivity that operates behind darkened glass at 50 Hz / 60 Hz light flicker immunity.

This sensor powered by 1.7v to 3.6v with a power management capability at low active current and low standby current for more technical details and product information please refer to the documentation below.
