Laser safety considerations
The
contains a laser emitter and the corresponding drive circuitry.
The laser output is designed to remain within Class 1 laser safety limits under all reasonable foreseeable
conditions, including single faults, in compliance with the IEC 60825-1:2014 (third edition).
The laser output remains within Class 1 limits as long as you use the STMicroelectronics recommended device
settings and respect the operating conditions specified in the data sheet.
The laser output power must not be increased and no optics should be used with the intention of focusing the
laser beam.

Ambient light sensor: VD6283TX
The
is a color sensor with advanced light flicker extraction. The light measurement is fast and
accurate, thanks to an individual ADC and a readout for each color channel. The
uses hybrid color
filters with precise responses, allowing accurate computation of the correlated color temperature (CCT) and lux
information. Additionally, the
has the ability to extract different light flicker waveforms from 100 Hz and
2 kHz, including LED square signals, that can run flicker operations simultaneously with ALS operations.
