8.2

Sensor Array

The device features a 5x5-photodiode array. On top and below the photodiode array there are two

photodiodes with dedicated functions such as flicker detection (

“FD”) and near- infrared response

(

“NIR”). The photodiode “C” represents a photodiode without filter and is responsive in the visible

spectral range

(“VIS”).

8.3

GPIO

The GPIO can be used synchronization input to start/stop the spectral measurement. It also allows

synchronizing the LED driver (LDR) with an external start/stop signal. Default state of the GPIO is

“output”.

8.4

Interrupt (INT)

The interrupt (INT) can be used to define thresholds and read-out the device only when the channel

threshold has been reached. The pin is active low.

8.5

LED Driver (LDR)

The LED driver is programmable and can be used to drive external LEDs. It is also possible to

synchronize the LED driver with an external start/stop signal via pin GPIO.
