Silicon Labs has introduced next-generation optical sensors that can be used to protect consumers from the harmful effects of ultraviolet (UV) radiation and to develop innovative touchless user interfaces leveraging high-performance proximity sensing and gesture recognition. Silicon Labs' new Si1133 optical sensor provides a cost-effective solution for adding highly accurate UV index measurement capabilities to a wide range of sports equipment and outdoor lifestyle products. The Si1153 ambient light sensor is optimized for operation in bright daylight conditions and extended range, allowing it to be used for gesture control and proximity detection applications in outdoor environments.
